How to Play F#dim on Piano
The F# Diminished chord sounds tense and unsettled. It stacks 3 notes: F# – A – C.
Two stacked minor thirds. Its fifth is squeezed a semitone flat, so the chord has no stable footing and wants to move.

Where it sits
One note of this chord (F#) is on black keys, so play it a little further back on the keys than an all-white shape.
Press all 3 keys at the same time. Keep your wrist relaxed and your fingers curved. The blue dots on the piano below show exactly which keys to press — they turn green when you play the right note.
