autograph in piano?

[likeflames22]

I found this autograph (looks like it to me) inside of my piano today, and I'm just wondering if it is anyone important. Does anyone knows or has any idea who this might be?

It says "RIP"  rest in peace ?  Maybe that's the date he keeled over when he was playing through Hanon.

Probably the piano tuner and the date they tuned the piano.  I've seen a few of those.

Maybe R.P. is register piano (technician) or regulated piano. 

That would be my guess.  A piano tuner might know what R.P. and 1/2 mean exactly.

I found a business card in one once too.

I've seen notes like these as well.  Sometimes indicating work done, or action parts that are in need of work.

I keep thinking "Ray Kramer" (band director, nationally known).  Maybe he tuned your piano long ago?

What kind of Piano is it?

[Bob]

I keep wondering what the R.P. 1/2 means.

It just occured to me that it could mean raised pitch 1-2 of a semi tone? That seems to make slightly more sense than regulated Piano 1-2.
