Arpeggio · F7♯5 · Piano
The F7♯5 arpeggio is F – A – C♯ – E♭ — chord tones 1 3 ♯5 ♭7. F7♯5 is a dominant that wants extra tension before resolving down a fifth; its sound is floating, whole-tone. Below, every F, A, C♯, E♭ on the two-octave keyboard is marked, with the root in gold. Press play to hear a one-octave arpeggio, or tap any note.
