I want to record my violin playing of a specific song and then play it back.....Can I do it all on the tablet or do I need to record on the PC and transfer. Also, do I need a special recording app for either the PC or tablet?

Generally, I find that the Android platform is not really slick enough for audio. Yes, it can play audio files, but as a recorder, it lacks quite a lot. I think you would be better to stick with the PC for this sort of thing.

You don't say what version of Windows you are using, but the more recent versions have in-built recording option (in Win 8 it's called the "sound recorder"). This might just suffice for your purpose, but there are plenty of third-party programs out there, from free to expensive, which will offer you far more flexibility.
