Yes, I have an iPad Pro 9.7 inch tablet that I've had for several years.Paper song sheets can be scanned using the PDF feature of combo printers at offices, libraries, print shops.
Can scan the book using the bulk feeder, or scan each sheet to its own PDF.
Some song software can separate a bundle of songs into individual songs.
Are there tablet protector cases similar to cell phone cases?
Cheers.
At first, I had an inexpensive case that had a keyboard & a loop for my stylus. It wasn't very secure, with only plastic corners to hold it in place. My 1-1/2 year old iPad Pro slipped out of the case and landed on a tile bathroom floor breaking the glass screen on the iPad.
I took it to a local Apple seller (No Apple Stores within 100 miles.) and they said they couldn't repair it. Without Apple Plan, they could send it to Apple and Apple would charge me an outrageous amount to fix it. If I had the Apple Protection Plan, I didn't, Apple would still charge me, at the minimum, for shipping both ways. Instead he sent me to a nearby game store that replaced the glass and pushed out the corner dent for $110!
I then bought a relatively expensive Otterbox Symmetry Hybrid Case* on Amazon. I went that route because I had one for my iPhone and it was amazing. The Otterbox case has served me well. The folding cover is getting a bit worn, but has protected my iPad on several long trips, in my music bag and from several falls for almost 5 years. Zero damage.
Make sure you know the correct size and model of your iPad to order the right case for it.
*Otterbox no longer makes the Symmetry Series cases, but have other models for the various iPad sizes and models.
