When writing their pieces, attention to detail can help composers ensure they include every aspect of the music musicians need to know in order to perform the piece correctly. A notation error can change the effect of a piece and confuse players. Some compositions, especially those for large orchestras or groups, require incredibly detailed instructions. For example, if writing for stringed instruments, each note might have its own specifications, like instructions on how loud to play the note, which direction the players’ bows should be going or which special effect they should apply.
