10 reasons I prefer practicing using ForScore on my iPad
The screen is self-illuminated and it doesn't matter if there is enough light in the room.
I can annotate in different colors, and in a range of thicknesses.
It's erasable and there are no imprints from old markings after I do erase.
I can get all the page turns on my own, using my bluetooth-connected foot pedal.
ForScore has a metronome built in.
I can add accidentals that look as if they are printed in the part.
I can duplicate and rearrange the pages, in order to facilitate repeats without turning back.
It is light and holds a basically infinite amount of music.
It has a clock built in, so I can keep track of the time to notate in my practice journal.
I can create "setlists" from my music, organizing it in rehearsal or concert order.
5 ways a paper score is still better:
It is wonderful to have a library of music on my shelves that I can browse, leaf through, and refer to for old markings and notations.
A score doesn't have a screen.
I can have two pages open at once.
It isn't subject to technological failures.
It is a low-tech, non-digital technology, just like the piano.
