There is this nice chart on Wikipedia that show the range of many instruments, probably more than a composer would typically use to compose music. Harps, Pianos, Bassoons, Contra-alto Clarinets, Tenor Wagner Tubas, Bass Trombones, Baritone Horns and Euphoniums are example of those that you need.      

By the way, some musical notation programs like Sibelius is able to highlight which notes are out of range for the associated instrument: if I wrote a C8 on a Bass Trombone line, it would automatically highlight the note in red. Furthermore, these programs normally contain at least a thousand instruments for you to choose, and I guess that's more than you ever need

What are the musical instruments that have the sounding range that has at least all notes on this range A#1-C5?
Is it possible to detect when an Android user uses the copy and/or cut functionality?

I have a client who's idea pretty much depends on being able to call a method inside the app whenever a user copies or cuts out a piece of text or an image, no matter whether the user is actually inside the app or not (though the app would be running in the background).

My initial guess would be no, but you never know. I haven't been able to find any clear information about it, so thought I should ask.
