Apologies if this has been covered elsewhere. I have read quite a bit but want to keep it simple. I'm looking to purchase a pair of mics to record my upright piano in my living room. The living room has a fairly low ceiling and doesn't sound great, but ok. A engineer friend of mine suggested a pair of Neumann KM 184's. After some reading I feel like these might be too bright/harsh?

I have no gear. I know nothing of any music software.

for my purposes here:

I have a u3 and would like to record it

I would like to get a keyboard and make noises with objects and experiment with those noises on keyboard and recording software

what kind of mic and recording equipment would I need to do this?

thanks!

Instrument: Yamaha upright
