Sheet Music App

On iPad, ForScore.

I’m curious what else will come up in this thread, but ForScore is what stuck for me.

forScore with a 12.9” iPad is what works for most people.  Smaller screens could work, but it’s it’s harder to read, of course.

For Android, there is Piascore, I think.  Dominic Cheli did an entire livestream about this.

Same for me. iPad Pro with forScore, and the Henle app. With these two I feel I am covered. 

I use MobileSheets on my android tablet and it works great! Very similar function as forScore. 

also +1 ForScore! It's great, you can annotate on multiple layers for study purposes, which you can also hide/show however you want, something you can't do with paper ;)

When I bought an iPad last year, I started with the 10" one. I discovered literally after using it for an hour that it just would not do for me - notes were way too small and uncomfortable to look at. I took it right back to the Apple Store and exchanged for the 12.9" one. Worth every extra penny, your eyes will thank you.

There's also bluetooth pedals you can buy which will sync with ForScore so you can "flip" pages using your foot. Good luck!

Consistently I have found iPadPro 12.9" with Foreshore to consistently be the combination use by Juilliard students/faculty and at the piano studios where I Practice in the city.   I use it at my home with my own piano.   It is a very easy combination with ability to annotate, respond to page turning (bluetooth pedals/etc), storage and retrieval of music and ability to catalog .   Easy use of stylus (especially Apple Pencil).   It also easily incorporates and syncs with all the major online sheet music sites.  The visuals are excellent

So I agree with what everyone else has said and it's been a very worthwhile investment though certainly is pricey.

Yes, I too switched to ForScore and the largest iPad years ago.

The only cons are the cost of the iPad (though they do last) and twice as many page-turns - unless you can afford two iPads, which I can't. 

The pros are massive: not just convenience, but the vastly increased scope for markings and analysis - transparent highlighting in variable shades and shapes allows for identifying entries, motifs, contrapuntal lines, harmonic rhythm... anything you like. And no more messy rubbing out!

After using paper for several years, I tried various digital approaches. Like nearly everyone here, I found ForScore on an iPad Pro (12.9") to work best. The many layers of notation in ForScore are great. I wish the downloadable scores that can be used directly in ForScore were better. Many have no fingering at all. I do like Henle, but prefer fingering from Alfred, so at the moment I'm using an Alfred score scanned into .pdf and imported into ForScore. Last I looked, I could only use Henle scores with the Henle app, which is not as flexible as ForScore, though it's making strides in that direction.

Page turns with ForScore on the iPad have gotten really easy. You can use a Bluetooth pedal, but with the iPad, since it has a front-facing camera, you can also wiggle your mouth in the right way to turn pages forward or backwards. You can also turn half pages, so you can see what you are playing on the current page while reading continuously onto the next page. There are many improvements still to be made on the electronics side that I hope ForScore will incorporate, such as listening to your playing and showing you where you are in the score, so when you have to look down at the keys, you have a marker for where to start reading again, for example. This and many other user-friendly improvements will doubtless work their way into the technology. Paper is old school, but necessary now and then.

I've been using an iPad Pro, Apple pencil, and an app called KeyScore to allow automatic page turns by recording your playing and "tracking" where you are on the page. Some glitches, but it's mostly fantastic.

I use digitalScore. It is better than forScore to me.

Dominic Cheli has had sessions on all this which may be of use. He also recommended Airturn Duo/BT500 pedal for turning pages, which is available on Amazon. The whole setup takes awhile to get used to. Have fun.

I use Goodreader for sheet music pdfs on an iPad.
