Tips for playing Gdim7 on piano
On piano, Gdim7 has two black keys (B♭ and D♭) and two white keys.
Notice the F♭ in Gdim7 (G B♭ D♭ F♭): each note of the chord takes its own letter (G–B–D–F), so the diminished 7th has to be written F♭ rather than E — the same key on a piano, spelled to fit the chord.
