It aint a grand so I guess its just a standup. Can you open the top of a stand up and close mic above the hammers?
I was thinking of maybe taking 2 pencil condensors and stereo micing the hammers maybe from medium distance is taht ever done?
and it is ROCK/POP music.
That is one option. It can work fine, but much depends upon the piano itself; some pianos sound "boxy" when miked this way.
There are a couple of other options as well. Try them to see what works best for you.
Option #2: The kickboard - the front "cover" underneath the keys and above the foot pedals - is usually made to be easily removable for tuning purposes. Another popular method is to remove this board and stereo mic from about 6" or so in front of the strings. This can sometimes be the most "documentarian" method for recording an upright. The downside is that it is the method most succeptable to noise from the footpedals.
Option #3: Some folks have found that miking the soundboard on the back of the piano from the rear has worked well for them. I have not tried this method yet myself, but quality souces have recommended this in the past.
Option #4: Mid-field miking can, with the right piano and the right room, yield a very natural sound from an upright, though usually best for a mono tracking. Something over the shoulder of the player. Off axis from the center, maybe somehwere even with or just beyond the left or right side of the piano and maybe 3 feet or so further back than the player's shoulder. Play with this a bit, thhough; the numbers are not exact, and depending upon the piano and the rrom, one side or the other can make a big difference in the clarity of the sound. Just walk around the positions in an arc while someone else is playing, maybe ducking your head up and down on occasion, and lust listen with your own ears for what sounds like a sweet spot.
Option #5: Any of the first 4 options combined with an extra track that catches the ambience of the room itself mixed in a lower volume. This works better in larger rooms with good reverberation, something where you can get at least 6-7 feet or more away from the piano without being crammed up against the rear wall. Again, expiriment with mic placement and face direction to see what sounds good.
With any of these options, it's usually a good idea to pull one side of the piano out from the wall a bit, mkaing a good 17-20 degree angle between the back of the piano and the wall. The idea is to reduce or eliminate standing sound waves that can otherwise grow between the piano and the wall and help muddy up the sound.
HTH, and good luck with the playing and the recording
