I spent a couple of days putting together some BIAB files based on the "Circle of Fifths" for practicing. Then I got the idea that it may be something that would be marketable considering there's no copyright protected material involved, plus a lot of work to put something together that's pretty useful for practice, ear training and basic sight reading. It may not be something people would want to purchase. That's why I'm asking you folks.

Here's the "spill".

"I’ve put together an extensive series of music files for Band In A Box that are focused on the “Circle of Fifth’s” and on “Diatonic Progressions”, intervals, chords, arpeggios, scales and modes.

First, let me say a few words about the Band In A Box music program for PC and Mac, hereafter referred to as BIAB. If you don’t have it, or you aren’t familiar with the program, you can find out more and purchase the program at http://pgmusic.com/ .

BIAB is a MUST HAVE program for any amateur or professional musician, singer or songwriter, regardless of your instrument or style of music. It truly is that versatile. What’s even better about it is that it’s extremely easy to use. You don’t have to be a “computer geek” to get a heck of a lot of fun and satisfaction from this program. It can be your “backup” 5 piece band for performing for your friends, or playing at a concert hall. If you’re a songwriter, it’s an invaluable tool. If you’re recording, it’s also a tool you don’t want to be without. Peter Gannon and his friends have put together a program that’s won too many awards to mention, and you can feel free to “Google” it to check for yourself.

And for the record, I’m not affiliated with BIAB, other than being a loyal and happy customer for the past 20 or so years. That’s why I’m offering these lessons in this format.

Now about the lessons:

They cover the “Circle of Fifths” in all 12 keys and they’re in “Diatonic Progressions” in each of the 12 keys. There are 7 different files for each key, all grouped together by key for easy access in BIAB. There are 84 files included. They consist of the following in each of the 12 keys and the music is written in the treble clef. All files are programmed to a MIDI style and can be easily changed to a style and tempo of your choosing in BIAB.

These files can be used to practice on your instrument or vocals. I originally programmed them to practice both at the same time. It doesn’t matter what instrument you play because with BIAB you can change the melody notes from treble clef to bass clef or simply change octaves with a couple of clicks of the mouse.

01. There is a “Diatonic” chord progression in each key. For example, in the key of C the chord progression is C, Dm, Em, F, G7, Am, Bdim, C. The progression then descends along the same path. The “ascending” and “descending” pattern is used in all 12 keys.

02. The “Diatonic” chord progression in each key is used with a variety of instruments providing BIAB solos in ascending and descending patterns.

03. The “Diatonic” chord progression in each key is used in ascending and descending patterns with only the “root” note as the melody.

04. The “Diatonic” chord progression in each key is used in ascending and descending patterns with the “root and third” notes as the melody.

05. The “Diatonic” chord progression in each key is used in ascending and descending patterns with the “root and fifth” notes as the melody.

06. The “Diatonic” chord progression in each key is used in ascending and descending patterns in “triads”, or the “root, third and fifth”, or “arpeggios” of each chord as the melody.

07. The “Diatonic” chord progression in each key is used in ascending and descending patterns in “scales” or “modes” of each chord as the melody. The first chord and scale would be the “Ionian” mode. The second would be the “Dorian” mode. The third would be the “Phrygian” mode. The fourth would be the “Lydian” mode. The fifth would be the “Mixolydian” mode. The sixth would be the “Aeolian” mode. The seventh would be the “Locrian” mode.

If you don’t have BIAB, I would strongly urge you to get it whether you purchase these lessons or not. It’s WAY too much fun to pass up. Take care and keep on playing and singing. People need more music in their lives."

Honest opinions please. If it is marketable, what would it be worth? $10, $20?
