John Mayer Plays Guitar

Sorry Picture Not Found

I did not know much of John Mayer until I watched a concert DVD recently.
I thought he was just some guy who had written a couple of radio hits that girls really liked, and that was about it.

But John Mayer is a guitar hero in the real sense of the word.
The breadth and depth of his playing is amazing, and he can play acoustic sets solo, or with his special John Mayer Trio band, or with his own full-on rock band. He is easily triple the musician I thought he was.

Words cannot decribe his virtuosity, you need to see and hear it for yourself,
which is exactly what I suggest you do by watching the videos below.

This is John playing some amazing Acoustic Guitar:

Now for a superb cover of the Jimi Hendix song : "Wait Until Tomorrow"
(I am so glad someone has done a version of this old favorite of mine).

Also definitely get yourself a copy of his superb concert movie DVD
"Where the Light Is" and watch and listen to it.

There is also a double CD available with a four and a half star rating on from 77 very impressive reviews.

Sorry Picture Not Found

Tracklisting for "Where the Light Is" DVD :

1.Neon (Acoustic Set)
2.Stop This Train (Acoustic Set)
3.In Your Atmosphere (Acoustic Set)
4.Daughters (Acoustic Set)
5.Free Fallin’ (Acoustic Set)
6.Everyday I Have the Blues (Trio Set)
7.Wait Until Tomorrow (Trio Set)
8.Who Did You Think I Was (Trio Set)
9.Come When I Call (Trio Set)
10.Good Love Is On the Way (Trio Set)
11.Out Of My Mind (Trio Set)
12.Vultures (Trio Set)
13.Bold As Love (Trio Set)
14.Waiting On the World to Change (Band Set)
15.Slow Dancing In a Burning Room (Band Set)
16.Why Georgia (Band Set)
17.The Heart of Life (Band Set)
18.I Don’t Need No Doctor (Band Set)
19.Gravity (Band Set)
20.I Don’t Trust Myself (With Loving You) (Band Set)
21.Belief (Band Set)

A Very Flash Matching Game

(Make sure sound is turned on while doing the above puzzle).

The above was made by following an excellent tutorial on how to make a matching / puzzle game located at:

It goes through step by step how to make a matching game in Flash, using Actionscript 3.0.

Also supplied are examples of the finished item each time, as well as the facility to download the source files for the tutorial.

At the heart of this game is the Flash "Dictionary Class" which is a means of making an array (or matrix) of as many related pairs of items as we need.

If you want to find out more about the "Dictionary Class" then click the following link: Information about the Dictionary Class

The nice thing about the Dictionary Class is it makes it very easy to make another game, simply by changing the dictionary entries and source pictures.
For example, here is a similar game about Australian football team mascots:

I thought that Adobe Fireworks was supposed to be Flash's "best friend", but this is not always the case. Eg. when I obtained an image from the internet, resized it in Fireworks to be 80 pixels tall, and saved it as a .png file type; there were problems. It could be imported, made to move around, but refused to match up with the text box I had set for it in the "Dictionary" part of the Actionscript code. The only way I could find to overcome this was to save the file as a .GIF type after resizing it. GIF files import to Flash, convert to Movie Clips, and function 100% ok in the matching game. (Note that .JPG files work fine as well).

So to bring images into Flash when building the Matching Game, the steps are:

1) Find an image on the internet and save it to our PC.

2) Load the image into Photoshop or Fireworks or GIMP, and resize it proportionally to be between 80 and 100 bytes tall. Save the image as a .GIF file type.

3) In Flash (with the matching game loaded in), do File > Import > Import to Stage then browse navigate to open and bring in the GIF file.

4) In Flash right click the selected image, and do Modify > Convert to Symbol
and make it a Movie Clip type, with the registration point as usual top left hand corner, and give it a meaningful name.

5) Very important to now type in an instance name, in the bottom left hand corner of the Properties panel, straight under where it says "Movie Clip". This instance name has to exactly match the name that is used in step 6.

6) With frame 1 selected on the timeline, press F9 to access the "Actions" (or do Window > Actions) and edit the top section of code to map the instance name from step 5, to the appropriate dynamic text box name. This is basically adding the required entry to the "Dictionary" we are using to drive this game.

These types of matching games would be great for Language teachers to use for vocabulary practice.

Maths teachers could make Geometry puzzle games about Triangle or Quadrilateral types, or Angle types, or Perpendicular versus Parallel and so on.

Science teachers could make puzzles about matching Animals to their family type, or rocks to igneous, sedimentary, etc types, and so on.

If you would like to download the source .FLA files for the two games used in this Blog Post, then click the link below:

Click here to download a .RAR file of resources.

Stay tuned for an upcoming "Part 2" post about Flash matching.
This will involve matching pairs of pictures to each other, rather than a picture to a text box.

Guitar Chords Online

Sorry Picture Not Found

One of my favourite chords, the E minor 9th.
Hmm... but what if we wanted to play a B minor 7th ?

What we need is a guitar chord dictionary.

There are many Chord Dictionaries and resources online for Guitar players.

One Chord dictionary is "ChordBook" at:

This site has a virtual guitar to show the chord, and if we click the chord or the "Strum" button,it will play the chord for us. This is good for listening to different chord inversions. The sound quality as well as the colors and graphics are well done and very user friendly.

Chord Book also has the same kind of set up but for
"Guitar Scales" at:

Another good site is "Chordie" at: which has a printable set of standard box shaped chord diagrams in root position.

On the Chordie webpage, we can then click on a chord such as the "A" chord, and it will then show in a new window the variations of this chord all along the fret board.

A third Chord Site which is quite good is"Chord Find" at which has a guitar neck that shows us the chord. We can also play the chord with a midi button that starts up Windows Media Player to download and play the sample.

Click the chord you want and it puts it on the fretboard picture; then clicking “variations” button will show the chord all along the neck in different positions.
We actually see a guitar neck and frets, rather than just a box diagram.

Chord Progressions

Once we know a few chords, we need to learn about how to put them together in groupings that sound good when played one after each other. This is called making a "Chord Progression".

There is some theory about why some sample Chord Progressions work at this page:

Here is a 6 minute video about basic chord progressions from Metacafe :

And now a 4 minute YouTube video about putting together some blues chord progressions:

And finally as featured on a previous post, there is "The Progressionator" that will help us make progressions in different keys, by telling us what chords to use.

There is also the "Progressionator" that can be used online for free, and will supply chord progressions and rythms for the standard patterns listed.

Try it out below:

(Note that you may have to use the scroll bars get it into view).
or you could just click this link:

So pick out some Chords, string them together with a strum or two, and just see exactly what you can do.

Wolfram Mathematica Demos

Sorry Picture Not Found

The above picture is not a bizzarre test pattern or color palette, but is a "Geometric pattern of Congruence" produced using Wolfram Mathematica.

So What exactly is Wolfram Mathematica ?

The full blown "Wolfram Mathematica" is powerful computer software that has to be purchased for several hundred US dollars.

However there are some great pre-made free demonstrations which can be downloaded to our own PC, and then played using the free Wolfram Player.

(We also have to download the Wolfram Player as detailed later).

From their own website, they describe Wolfram as follows:

Founded by Stephen Wolfram in 1987, Wolfram Research is one of the world's most respected software companies, and a well known powerhouse of scientific and technical innovation.

At the center is “Mathematica”: Wolfram’s core product that launched modern technical computing and has now become the world's most powerful global computation system. With millions of dedicated users throughout the technical and educational communities, “Mathematica” represents a unique blend of major research breakthroughs, outstanding user-oriented design, and world-class software engineering.

The "Wolfram Demonstrations" website page is at:

These mathematical demonstrations can be previewed and then downloaded.

However, to play them and use their control sliders, we need the "Wolfram Mathematica Player" installed, and this can be easily downloaded for free on the demonstrations page.

On the demonstration we are viewing, in the top right hand corner, there should be a clickable download symbol that looks like this:

Sorry Picture Not Found

We can click this symbol and download and install the free player onto our computer.

For Mathematics Teachers:

The idea is to search and find a demonstration that is useful, and then download that file.

If it is your first time downloading a demonstation, then you will also need to download the free player and install it onto your computer.

Here are some screen shots of some useful demonstrations that I have downloaded and used:

Addition of Fractions

Sorry Picture Not Found

Using the slider controls we can create many diferent denominators and numerators to visually show how a fractions sum answer is derived.

Multiplication of Fractions

This demonstration allows any fraction to be multiplied by a whole number.

Sorry Picture Not Found

This can be used to identify equivalent fractions.

Get The Equation of the Line in Record Time

Sorry Picture Not Found

This is a mathematical activity designed to help students practice finding the equation of a line in slope-intercept form. Press the "go" button to start the game. A green line will appear; select the button with the equation that describes the green line before the time runs out.

Selecting the correct button will give you a new line, but less thinking time.

This activity is designed to work well with interactive boards, as a classroom activity. (It will not work on this blog post, because it is only a screen dump).

The Gambler's Ruin

Sorry Picture Not Found

The gambler starts with an "i" unit stake and the casino or house starts with "c" units. They repeatedly play a game for which the gambler has a fixed probability "p" of winning and the winner gets 1 unit from the loser.

Play continues until the gambler "succeeds"
by acquiring i+c units or is "ruined" by dropping to 0 units.

This Demonstration computes the probability that the gambler will succeed by breaking the bank. Subtracting this probability from 1 gives the gambler's ruin probability. The theoretical expected number of plays of the game until success or ruin is also computed and a simulation gives empirical results for the various parameter values.

In the example shown above we used p=0.474, the player's
probability of winning an "even money" bet in American roulette.

There are many other free demonstrations available from Wolfram.

So take Little Red Riding Hood and all her friends along to see
the Big Math Wolf.

Very Powerful Guitar Chords

Sorry Picture Not Found

AC/DC - Now there's some very nice powerful rock music.

We can get a bit of power into our own guitar by using "Power Chords".
There is plenty of information about these chords on the internet, and here is Passy World's pick of some good material to aid your guitar education.

Power Chords are basically 2 or 3 notes that have been taken from a barre chord, and are played as a group on electric guitar, with distortion or overdrive liberally applied. They are the basis of many rock songs, and musically they are based on 5th intervals.

Here is an 8 minute movie from YouTube about the basics of Power Chords:

Here is a really good explanatory written lesson about Power Chords on a web page:

This same site has a good summary page of Power Chord Diagrams that can be printed out. This printable Power Chords Chart is located at the address:

This lesson about Notes on the neck will help visualise how we move up and down the neck on the E and A strings to form Power Chords:

Here is a rundown on how to create 3 note power chords, from their corresponding Barre chord:

Here is a summary diagram of standard 2 note Fifths Power Chords:

Gracefully Identifying any Tune

Sorry Picture Not Found

Whenever I use Itunes, or Creative Media Player, or Winamp, to play an audio CD or any MP3 files, on my computer at home, a "Gracenote" icon briefly appears on the screen, and instantly all of the artist and track information appears displayed in the media player.

I have been amazed by what Gracenote can identify. Any CD that is placed into the home PC is usually fully identified, even Hal Leonard CD's that accompany learning guitar books are fully detailed with all track names. The other amazing thing is the speed at which Gracenote links to the internet and completes this task.

I have been wondering for a while what exactly Gracenote is all about, and so I decided to research this matter further.

Here is information about the Gracenote music identification process from the
Gracenote website at : .

Gracenote "MusicID" is the industry standard for digital music identification for both CDs and individual music files.

Gracenote MusicID® provides fast, accurate, and reliable music-related content for people all over the world. Gracenote's technology is relied on by many of the world's leading consumer electronic devices and media software applications. Gracenote MusicID uses a multi-step recognition method to enable identification, categorization, and organization of digital music. Regardless of source or format, Gracenote® gives music fans the tools to manage and enjoy their music collections.

As of 2009, Gracenote databases held information on nearly 100 million audio tracks and more than a million videos.

The Gracenote Media Database supports both networked and embedded applications for the home, car, portable, and mobile phone markets. It's the world's largest global media database of music and video metadata.

Gracenote pioneered CD recognition technology in 1995 under the name CDDB®.

In addition to the original audio CD track and artist recognition services, Gracenote now also provides:

MusicID File (Search by File Fingerprint) - A digital audio file tagging service that computes an acoustic fingerprint for MP3 and other audio files and matches it against a fingerprint database.

MusicID Stream (Search by Audio Fingerprint) - Similar in concept to MusicID File, this service computes a more robust acoustic fingerprint in order to identify a song by listening to a sample anywhere in the middle.

VideoID DVD, VideoID Blu-Ray, VideoID File - The video counterparts to the audio services for obtaining meta-data about a disc or TV episode. Like music CDs, table of contents data are used to identify DVD and Blu-ray discs, and a video fingerprint is used to identify video files.

There is a good interview with one of the founders of the original Gracenote company at this address:

Gracenote is based in California and was aquired by Sony corporation for
$ US 260 million in June 2008.

Itunes and Winamp

Both the Itunes and Winamp music players utilise Gracenote.

We can download Winamp for free from : .

Winamp runs Gracenote, connecting to the Internet, and performs a search whenever we put a CD into the PC. For example, here are the results for an Aerosmith compilation CD that I made for driving in the car.
(Yes I do own all the original CDs, as I quite like Aerosmith).

Gracenote "Lyrics to Go"

Gracenote "Lyrics to Go" is a web page widget that puts a search engine onto our blog or web page like the one shown below:

Try out a search in the above window by typing in "fire in the sky" and clicking the search button. ("Smoke on the Water" by Deep Purple should be found, along with several other songs that also contain these same words).

If we then click on the "Smoke on the Water" song title that is displayed, a new window will open that will contain the full set of lyrics to the song.

Alternatively, we can perform the Lyrics Search at the Gracenote Website: .

With Gracenote's Lyrics To Go search widget, we have instant access to the world's largest legal database of lyrics. It's simple to implement onto any webpage and lets users search by Lyric Text, Artist Name, or Track Name.

Lyrics to Go is a great way to identify a song's title and Artist, if we only know a few of the words to a song. This is often the case where we might have heard a great song on the car radio, but can only remember the chorus line.

For example,typing in "get your motor running" soon brings up: "Steppenwolf - Born to be Wild", as well as the lesser known : "Shasta Beast - Eagles of Death Metal", which also contains these exact same words.

If we cannot find the lyrics we need using Gracenote, another great site for song lyrics can be found at: .

Gracenote Music Map

There is also the Gracenote "Music Map" that shows what music is currently popular in different countries and states anywhere around the world.

Click a country on the map below, and then scroll to the right to see the current
Top 10 Artists and Albums. (Or use the link above to go to full page view).

For example here are the results of a recent check of the latest Top 10 Artists and Albums in Iceland :

So where ever you are in the world, Gracenote is there to help guide your musical journey.

MJW's Flash AS 3.0 Avoider Game

The Michael James Williams Avoider Game was built from a multi-part set of Tutorials that start on this webpage:

and continue to a conclusion at the top of this page:

The tutorials run down the page from final part to beginner part, and so we have to go to the very bottom of page 2 to get to the very first tutorial.

We have to be careful when going through the listed Tutorials, because some are written in the old Actionscript 2.0, and the others are the latest Actionscript 3.0 (AS3) tutorials.

There is a page that has a master index of all the AS 3.0 steps at:

and I suggest that people use this page to access the tutorials and build the game.

The game being reviewed here was developed in Adobe Flash Actionscript 3.0 and Michael does a great job of building the game up step by step with brilliantly detailed instructions and explanations.

In total there are 12 tutorials that sequentially build up the full game in AS 3.0 :

AS3 Avoider Game Tutorial, Part 1: Basic Set Up
AS3 Avoider Game Tutorial, Part 2: Multiple Smiling Enemies
AS3 Avoider Game Tutorial, Part 3: Game Over
AS3 Avoider Game Tutorial, Part 4: Menus and Buttons
AS3 Avoider Game Tutorial, Part 5: A Score and a Clock
AS3 Avoider Game Tutorial, Part 6: Several Small Improvements
AS3 Avoider Game Tutorial, Part 7: Keyboard Control
AS3 Avoider Game Tutorial, Part 8: Adding a Preloader
AS3 Avoider Game Tutorial, Part 9: Music and Sound Effects
AS3 Avoider Game Tutorial, Part 10: Multiple Levels
AS3 Avoider Game Tutorial, Part 11: Saving and Loading
AS3 Avoider Game Tutorial, Part 12: Garbage Collection

Doing these tutorials is a great fun way to learn ActionScript 3.0.

In the "Alien Game" at the start of this Blog post, we have only completed parts 1 to 6 of the above Tutorials, due to time constraints.

(Eg. Have to eat sleep work play guitar, and do other stuff as well).

Sometime later on it would be fun to add the other parts to the game, especially bonus objects (like coins or jewels) that the green alien could bump into and collect to earn extra game points. Levels and Lives would also be great.

The instructions on the MJW website are fully detailed, and he has a nice copy to clipboard feature on all of the code snippets which saves a lot of typing time.

He also has downloadable zip files for each part, so that when things are not working, we can download his AS 3.0 Class files, and compare them line by line with our own code.

If you would like to download the .FLA Source file, as well as all of the AS 3.0 class files for the Passy World version of the game, then click the link below:

Click Here to Download .RAR file of Source Code from Passy World

There is another page, where we can play amazing variations of his Avoider Game that people have developed, such as a great game called "Robot Saga: Escape". These games can be found and played online at the Avoider Game homepage at: .

Michael James Williams is definitely one of the flashest game programming teachers to be found on the Net.

Passy World rates his tutorials as 12/10 !

So stop avoiding Actionscript 3.0, and get right into it !

Flashy Free Guitar Accessories

The above interactive Flash Animaton is a free online guitar tuner from "hotfrets".

We can click on a string, and it will sound, so that we can tune our guitar.
We can also download this tuner from the hotfrets site to our desktop.

The "hotfrets" site is located at:

It has quite a few nice guitar learning tools, that have all been created using Adobe Flash. Some are for free, but the others require a monthly membership fee.

A cut down version of their full Tabulature writer is also supplied on the site, and shown below:

We can click on the guitar fretboard where the notes are that we want to play, and then it will write the tab for the notes underneath on the six string lines.

Try it out by clicking on the fretboard above.

A really nice thing is that once the current tabline is full, we can highlight it, and use Ctrl-C to copy it into memory. We can then Ctrl-V paste it into Notepad, and save the tab for later printing. We can clear the tabulator, continue the tab, and then copy and paste this into our notepad document. So it is indeed a very user-friendly tab writing tool.

There is also the "Progressionator" that can be used online for free, and will supply chord progressions and rythms for the standard patterns listed.

Try it out below:
(Note that you may have to use the scroll bars get it into view).
or you could just click this link:

There is also the "Arpeggiator" that can be used online for free, and will supply all of the notes that make up a particular chord.
The notes are shown on the neck, and can be plucked with the mouse pick.

Try it out below:
(Note that you may have to use the scroll bars get it into view).
or you could just click this link:

There are also a few free lessons at the site such as Eric Clapton "Cross Roads"
at :

If you need a free online metronome then try these links:

The advanced metronome is almost like a mini online drum machine.

The Guitar Tuner, Tab Writer, Progressionator,and how to play songs items at hotfrets have all been created using Adobe Flash. I show them to my computing students as examples of the extent of the power of Flash.

Music naturally runs in a timeline when it plays, and so Flash is well suited for graphically representing music and translating it to Guitar tabulature.

Free Interactive Fun Mathematics

The "National Library of Virtual Manipulatives" ("NLVM") is a set of resources that run as interactive online mathematical demonstrations, puzzles, and games.

(The above image is a solved puzzle where the geometrical shapes had to be arranged in a certain red and blue repeating pattern).

Mathematics is not a spectator sport. All too often, traditional instruction fails to actively involve students. One way to address the problem is through the use of manipulatives, physical objects that help students visualize relationships and applications. This is what the "NLVM" hopes to provide.

The "NLVM" Homepage is located at .

This index page consists of a matrix of options for different branches of maths, mapped agianst different year levels. We simply position our mouse on the square we want (for example Year 6-8 Algebra), and then click to go the the list of resources.

Here is a window into the actual home page:
(Use the horizontal scroll bar to see the Y9-12 column)

Basically, using the "NLVM" is simply a matter of getting in there
and then picking and clicking to explore how the different items work.

For example, here is an interactive Algebra Factor Tree :

(Enter numbers into the window below to try out building the factor tree)

If we scroll down to the bottom of the tree, we can change from "Computer" to "User" and enter our own numbers to factorise. We can also do two factor trees per screen if we want to.

Here is a view of all of the items that are contained in Level 6-8 Algebra

Here is a nice Coin Toss simulator and analyser for Probablility:
(Press the "Start" button and let the simulator run to completion).

There is lots more to explore in the "NLVM", and so why not ditch the Maths books for a lesson and check it out.

The Day the Megabytes Ran Out

Sorry Picture Not Found

A picture that is worth at least a thousand bytes.

Sadly there has been no internet for several days here at Passy World, because we overshot our monthly gigabyte download limit.
(See above graphs).

What pushed things over the limit was the weekend we finished building and setting up the new gaming computer. Setting up this new PC involved downloading several gigabytes of patches for all of our games, as well as a lot of Adobe updates.

But in the end it has all been well worth the effort, because the gaming performance of the new machine is superb !
