So on the sheet music I was playing there were these notes with x's on top of them. Like on the stem. What am I supposed to do? Do I just not play them? This is for the piano by the way.
Were this for guitar to play, it would show muted notes - notes of a time value but no actual pitch - a 'click'. It's not possible to do this on a piano, so I'd say it's a combination piece of music.Had the x been in front of a note, like a # or b , then it WOULD be a double sharp, the note being played a tone above the basic note.These are quite rare, so you wouldn't find lots anyway, and generally found in 'sharp' keys. Don't think knowing what key the piece is in will help. It looks like it changes through many keys, is it occurring in one particular part ?
