The problem of performing music using sheet music are manifold. On the one hand, making music easy to see and follow cuts down on rehearsal time and produces better performances. Over the years I've been careful to add cue notes; arranged lines of music so that rehearsal letters are placed at the left of the page; made sure not to put too many measures on one line of music to keep chord changes from being cluttered; spaced drum parts to reflect the length of a musical phrase, and on and on. On the other hand, these layout strategies lead to more pages-per-part. Now the composer has to worry about the practicalities of dealing with a long part on a music stand. Occasionally I've changed notes to rests just so the musician can take the time to flip over the part or turn pages. Sometimes I wish that musicians had page turners so I wouldn't have to deal with the part layout at all. The Manhasset folder makes it possible to have 4 pages visible on the stand instead of the usual 3 pages. This is a great help, but it significantly clutters up the performance space and consequently pushes musicians apart. Moreover, the big folder hides the performers from audience views.
