    I am currently trying to learn all my scales for my grade 8, have cracked all the majors and minors, (sort of!) i can work out the dominant sevenths (1st note is the dominant, than the arpeggio with the added 7th) and i can work out the whole tone scales by picturing the keyboard, but i dont really know how to work out the diminished 7ths.

    Any one got any ideas how to learn the method of working out the scale, instead of just the notes? (does that make sense?)

    Minor 3rds...dom 7ths are built on these. They are easier to play than dom 7ths, well thats what I think :D

    so for example:

    C dim7 = C Eb Gb A (I hope!)

    There are only 3 possible Diminished 7th scales...

    F# A C Eb F#
    B D F G# B


    Bb Db E G Bb...

    Simple as that really?

    Or you can just count up 4 semitones from the note you're on (including the note you're starting on, i.e. C, C#, D -> Eb)
