The Ipsilon Vocal Excerpt Library

The first library of modern editions of scores and parts for arias, ensembles, and choruses — researched, proofed, corrected, and ready to put on the orchestra musicians’ stands.

No more writing start- and stop-points, or cuts, into scores and parts by hand!

Each order is customized to your requests:

– Start- and stop-points
– Cuts
– Keys
– Page size and format

The Ipsilon Vocal Excerpt Library (‘IVEL’) was founded, and is supervised, by conductor John Yaffé, who assures that these editions demonstrate the highest level of professional integrity, and that they are idiomatic and performer-friendly in every respect.

‘In the future, I’m just going to throw away our old sets of materials and order from Ipsilon.’
