A small saltire-like cross, raising a note by two semitones.
Also known as: Double sharp, X music symbol, Cross music accidental
๐ช raises a note by a whole tone. It looks nothing like two sharps, which is the point โ it is a distinct mark so that a reader does not misread it as an ordinary sharp.
Raises the note it precedes by two semitones, a whole tone.
Contexts: Music
Is drawn as a compact cross rather than as a doubled sharp, so that it cannot be misread as an ordinary sharp at speed.
Contexts: Music
Appears where the key already sharpens a note and the music needs it raised again, which is why it is common in remote keys and rare elsewhere.
Contexts: Music
Two short diagonal strokes meeting at the centre, each thickened at both ends, so the figure reads as four wedges arranged around a single point.
