Thanks for your support!

A. Alternate (slowly) F# to C chords, and improvise a spooky melody around it.

If you want some dramatic thrusts, diminished 7th chords will work, you know, like C combined with Eb, Gb and A.

Original Question

How to find a diminished 7th chord on the Piano?

Q. Please give me the diminished 7th chord on the piano for C.

Thank you.

A. On C a diminished 7th chord would be

C - Eb - Gb - Bbb (B double-flat, in other words, A natural)

C - Eb - Gb - A natural

A diminished 7th chord is simpyl all minor 3rds (one whole step and one half step each). How it's spelled (the note names) depends on the role in which the chord is functioning

Original Question

What is a Gflat augmented7 on the piano?

Q. also what is a Bflat 9t, could you spell out the chord for me? its written wierd.

A. It is a Gb aug chord with a minor 7th added to it: Gb Bb D Fb

B flat 9 (is the "t" a mistake?) is Bb D F Ab C
(there is also Bb add9 = Bb D F C)
