楽譜
Sheet music can be used as a record of, a guide to, or a means to perform, a song or piece of music. Sheet music enables instrumental performers who are able to read music notation (a pianist, orchestral instrument players, a jazz band, etc.) or singers to perform a song or piece. Music students use sheet music to learn about different styles and genres of music. The intended purpose of an edition of sheet music affects its design and layout. If sheet music is intended for study purposes, as in a music history class, the notes and staff can be made smaller and the editor does not have to be worried about page turns. For a performance score, however, the notes have to be readable from a music stand and the editor has to avoid excessive page turns and ensure that any page turns are placed after a rest or pause (if possible). As well, a score or part in a thick bound book will not stay open, so a performance score or part needs to be in a thinner binding or use a binding format which will lay open on a music stand.
