Depreciating a Piano

[JaP]

I am a professional musician and I just bought a $71,000 piano that I'd like to write-off. There are two competing considerations. On the one had, I am financing at 9.25% (which is about $15 of interest per day!!) so I want to use the write-off to pay off as much of the piano as quickly as possible. On the other hand, I will make much more in 2012 than I will in 2011. Is there a way to write-off half of it this year and half in 2012? Or am I stuck choosing either 7 year depreciation or a 179 deduction.
