Ch. 5 – Chord Symbols

We need to learn chord symbols. They are a musicians acronym. They represent the multitude of harmonic colours we can add to our musical experience. The following two links handle spelling out chords very well

    I always thought C11 was without the E in it. The E and F clash and also confuse the type of chord it is: dominant, tonic or sub-dominant.

    What do you think?

    I agree most of the time. But the rules for finding valid notes and voicings are the same.
    You build on the 1-3-5-7-9-11-13
    The melody dictates what happens sometimes. This complexity of harmony is typically used by jazz pianists.
    I know it can be overused and some people never get used to it.
    Try C-G-E-Bb-D-F but resolve it with F-A-C-E or F-C-E-G the parallel movement treats the clash like it was meant to be.
    But maybe only half the population can reach a tenth so those kinds of voicings don’t get used much.
