Tony,

The below information might be useful when simplifying the auto-generated intro...

From the perspective of the large majority of popular music, most chords that are used are based on either major or minor chords. Any numerals that are added (e.g. 6, 7, 9, 7b9, etc.) are extensions of those major and minor sounds. In other words, the major or minor sounds are the cake and the numerals are the icing and decorations.

With the above in mind, simply leave out the numerals and keep the major or minor chords that remain.

Thus, a progression like: C6 F2 Dm7 G7 is based on C F Dm G and may be comfortably simplified to this.


Quote:
NOTE: chords that cannot be changed into simple major and minor chords are those that contain the following...

1. sus (such as Gsus, Asus4, Dsus4b9)
2. dim (such as Cdim, Adim7, D°) - the ° symbol is often used to mean 'dim'
3. b5 (such as Bmb5, Am7b5)
4. aug (such as Caug, G+) - often the + symbol is used for 'aug'

While 'sus' chords are reasonably common in pop music, the others (dim, b5, aug) are rarely met.


Hope this helps,
Noel
