How can I mike a piano with a PZM without using tape?

I'd like to permanently mike a grand piano with a PZM, but I don't want to gaffer-tape the mic to the underside of the lid. Are there any other placements that work?

• Place a PZM on the soundboard under the strings.
• Place a PZM under the soundboard on top of the cross brace, about 2/3rds up the keyboard. With a little high-frequency boost it sounds great.
Thanks to Peter Patrick and Ivan Beaver of Syn Aud Con for this advice.
