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

Here is the space, a large classroom:20' x 40' long, 12' high.

Hi guys!

Does anyone have comparison advise for these two condenser mics? I am looking for a pair, mainly to mic upright piano. As I live in Australia it is cheaper for me to buy NT5s though the reviews I have read seem to favour the MK012s.
