KeyScore is a full-featured digital sheet music app and is an amazing tool for any musician from novice students to professionals. The app provides a wealth of features to let you scan, import, annotate, organize and play all your music from your iPad. With KeyScore's intelligent features you get amazing functionality including automatic page turning, a music-aware camera-based scanner, smart audio playback and more. Key Score comes with some music scores built in so you can instantly try it out! And then, easily add your own music!

*** Automatic Page Turning ***
Automatic page turning and tracking is a novel feature KeyScore offers to musicians and of particular use to pianists. KeyScore can extract musical information from a Score and create an audio model. When tracking is enabled, the audio model is consulted to allow the app to track your playing. As you reach the bottom of a page, part of the next page will be shown. When you reach the top of the page, the page turn completes. You can keep playing with both hands without visual interruption. No more need for a page turner or bluetooth foot pedal!

*** Scan and Edit ***
- Use the camera scanner feature to convert your physical sheet music.
- Deskewing and uncurling of the photo handles problematic images typical from a music book.
- Automatic background detection can correct shadows.
- Automatic staff detection and margin size settings

*** Audio and Video Tools ***
- Recording & Playback: General purpose recording and play-back tool and enables KeyScore to record your playing anytime you use tracking mode. Since KeyScore can read and understand the written music, it lets you play back from anywhere in the score just by tapping the measure you’re interested in.
- Import Audio: Import external audio, which may be a professional recording. Like with your own recordings, KeyScore aligns the written music with the audio allowing you to easily listen to just a measure, a line or the whole recording and compare between multiple recordings.
- Video Export: Create and share movies of your playing while the written music is displayed

A Life Saver for Performers and Teachers

This app is a amazing. Imagine having your pages turn without the use of a foot pedal! This is a life saver for pianists and especially organists who already have enough to do with their feet. I am a classical pianist and this app worked for contemporary pieces that had changing meters and unusual sounds. Also, your scores can be organized in one place so that you have them with you when you are away from your studio. You can annotate your score and share it with someone, as well as record what you are playing to share with someone (or not!). The scan feature is so helpful.....no more fussing with the scanner on your flatbed printer. Just take a picture and it gets converted to a pdf.
Some of these features require a pro features subscription, but absolutely worth the money. You get to try it for two or three months free, so there is really nothing to lose. Give this a try.

Great customer service

I love this app, but I had some trouble getting clear images when I scanned a particular piece. As a result, the page turn feature didn’t work consistently. When I mentioned that in my previous review, one of the developers responded and encouraged me to contact them via email which I did. After several email exchanges and following Tim’s suggestions, the page turn feature is working almost perfectly on that one song. I suspect that the biggest problem is that my iPad is pretty old, but Tim did everything in his power to help me get the best result possible. Not only is KeyScore a great app, but their customer service is the best!

As someone who's played a long time but only 2 years of lessons I never learned the left hand except for chords, always struggled with trying to flawlessly turn page. So my posting ability is the melody and chords. At first it wasn't letting me do what I want due to my limited ability so I contacted them about my problem. Right away Tim got back to me and over the course of a few days and many update emails during the day, I updated it for people like me with limited ability! Thank you so much Tim for your help and solving a problem I've had for years!!
