Additive meter

From Wikipedia, the free encyclopedia

In music, Additive Meter refers to a patten of beats that subdivide into smaller, irregular groups. It is common in Eastern European musics, and contemporary compositions attempting to emulate such a sound. For example, a time signature like 9/8 is normally subdivided as 3+3+3, or nine eighth notes with three to a beat. However, the composer or conductor may specify an additive meter for passages of music where it is more natural to conduct with a different pattern. Hence, a meter like 9/8 may instead be subdivided as 2+3+2+2 for musical effect; most commonly such an additive meter is used when accented notes or syncopated patterns do not match up with the normal subdivision.

David Holsinger's In The Spring, at the Time when Kings Go Off to War features many non-standard time signatures (10/8, 7/8, 5/8) for which Holsinger specifies additive meter as appropriate (e.g., a 10/8 measure may be given as 2+3+2+3 in the sheet music). Alfred Reed's Armenian Dances (Part I) contains a movement written in the nonstandard time signature of 5/8, which can be conducted as either 2+3 or 3+2 depending on which is more musically natural.
