Thanx. AAMOF, I have a new piano number I've been working on since Sunday.
Well, you can mic a piano with a single SM57, or two mics is probably more of a standard. However, nothing's a hard & fast rule, other than what sounds best at the time, or sometimes what's most convenient.
On a serious piano session, & for best results, I would remove the piano's top-front wooden panel, to expose the string section and sound board. Then place one or two mics about 12" off the strings from the front, L & R, set up on either side of my shoulders, either pointed directly perpendicular to the strings, or angled slightly toward the center.
I believe this would be a "standard" setup of mic'ing an upright piano with 2 mics, although a single mic could be used in a center position.
However, sometimes you do just what's convenient. F/I, on my most recent piano track, just last Sunday, I used a single mic on the piano, pointed up into the gap between the front cover and keyboard, right into this 2" space, just comfortably to the right of my right hand, & pointed slightly upward from the right to the left toward the strings. It's an acceptable mic placement, but I'd have gotten better results to fine tune the EQ more, at the time. It's a decent track, though.
I'll scan and post a pic of what I'm talking about, "standard upright piano mic'ing".
Pic: "standard" mic setup for upright piano,... from "Musician's Guide to Home Recording", by Peter McIan & Larry Wichman. I could probably take a better picture.
See: It looks as I've described, except these mics are boomed in a bit toward the center, and angled out. It's a relatively minor difference from what I described, but you get the general idea.
Angle mics out from center a bit to isolate Hi/Lo a little on L/R mics, or angle mics in to get a more cohesive tone in both mics. Alternately, you could spread the mics a bit & angle both mics directly toward & perpendicular to strings. You'll get a subtle change in the mic'ing effect by small changes like this.
There's nothing set in stone, but there are some guidelines, and minor differences are done to taste. I've occasionally used straight mic stands placed on either side of the piano bench, angled a bit inward, but a boom stand aids in the real nitty-gritty of mic placement onto an upright piano.
Thanx for listening, & thanx for asking!
