Learn your music and run rehearsals right from your mobile device using the new RehearScore App! Sometimes, finding a rehearsal pianist that meets your budgeting and scheduling needs can be challenging. The new RehearScore® is a complete digital rendition of the Piano-Conductor Score, sequenced by a top Broadway accompanist, precisely the way the composer intended. Every musical number (including scene changes, dance music, and underscoring) is recorded in its entirety so you can rehearse even if you don’t have a pianist. ● Every cast member can have access to RehearScore® ○ Simply download the App right from the App Store to access your show! ● Conduct dance or choral rehearsals. ○ With the ability to change the tempo and loop a dance break, you can run multiple rehearsals at once without the need of a separate pianist or recording. ● Find the right key – transpositions are easy. ○ Adjust your songs into the key that best suits your performer. ● Isolate, increase, or remove any particular vocal line. ○ Because each singer’s part has been recorded on a separate track, it can be played back with or without accompaniment (or louder or softer, relative to the accompaniment). ● Click and jump to any measure. ○ Measure numbers match each individual score. ● Add cuts and vamps. ○ Edit the songs down to the specific cutting you need and find the perfect number of vamps you’ll need in each song. ● Save your changes. ○ After adjusting the songs, save your changes to distribute to your cast and crew.
