Re: Arpeggio question
Reply #1 –
There are more than two ways. Much depends on the surrounding music. Normally, one does not begin an arpeggio until after prior notes/rests are performed. The arpeggio normally ends before any subsequent notes/rests for that hand.
One method to indicate an arpeggio that begins before the beat is to write it out using grace notes that appear before the beat.
Sometimes, it is obvious that the composer intends a harp effect and the performer will make an effort to sound like a harp.
Sometimes, the sign appears because it is obvious that a normal hand is not large enough to play the notes in the chord at the same time. These are usually played as quickly as is possible.
