my singing is awful but i love this chord so much so idk press the flag the F# half diminished chord consists of the root (F#), the minor 3rd (A), the tritone (C), and major 3rd of the tritone (E) in other words the notes of this chord are in this order: F#, A, C, E you might hear a phantom note (A an octave above the one i sung) dont worry i hear it too its not actually there
