## What is MTI RehearScore?

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.

### 4/5 — It was great!

*2026-07-04*

I don’t know what all these bad reviews are about, I personally really enjoyed the app and thought it did its job well! All the songs have a vamping effect that you can turn off if you don’t want to rehearse that part and it plays the vocal parts on the piano (you can turn that off as well)! Over all great app!!

### 3/5 — Cool app with a lot of potential

*2026-03-21*

Super useful for practicing but only works 50% of the time. It won’t play anything unless your phone is off silent which is annoying and sometimes it just doesn’t work at all. Could be a lot better.

### 3/5 — Needs lyrics

*2026-03-18, version 1.1.4*

It would be helpful if there were lyrics with the songs

### 1/5 — Sound not working

*2026-03-18*

My volume is up, it appears that the track is playing, but why is there no audio? I’ve refreshed the app, downloaded it again, other people in my cast seem to have it working perfectly. Ive seen another review like this so please get this sorted out.

### 3/5 — Good but could be better

*2026-02-20*

The app has a lot of potential but nowhere in the entire thing. Is it labeled that in order to hear sound your phone has to be off silent and most of the time when I’m using the app I’m at school and I don’t want my notifications going off for everyone to like here and be a distraction so my phone’s not to be silent. It took me a week and a half to figure it out

### 1/5 — Inefficient Horrific Program

*2026-01-29*

This app is horrific - audio quality, usability, flexibility - nothing works. The fact that it isn’t available for use on laptops further proves the point that it isn’t actually intended to be a useful program. The creators of this and the individuals pushing its use instead of allowing theater educators the freedom to access high quality tracks on the device that works best in their space should be ashamed of the way they are making excellent theatre less accessible in the communities they “serve.” The rights holder monopoly has gotten out of control.

### 3/5 — It’s okay

*2026-01-08, version 1.1.4*

I need to know how to play vocal parts I can’t hear my part to practice it

### 1/5 — Delete and reinstall

*2025-10-28, version 1.1.4*

Been using the app for five weeks now and I have had to uninstall and reinstall because the music disappears.  I can see the measures progressing but I hear nothing.  I have learned to keep my username and password close at hand.  If not for this annoying defect it works pretty good when it works

### 1/5 — doesn’t work

*2025-09-04, version 1.1.4*

so it doesn’t work!! how can i rehearse if it doesn’t play music❤️‍🩹

### 1/5 — No Sound

*2025-07-09*

Sometimes I go to use the app and I can’t hear anything. My sound is on and up and all settings are on. You sometimes have to close out the app and/or start the phone. I wish there was a website version available for time like this. Please fix these sound bugs!
