best affiliate program for piano sheet music niche

Hello,
I am currently monetizing my piano sheet music site with AdSense, but piano sheet music links pay me about 5-6 cents per click.
I am looking for something that will pay higher. It doesn’t have to be piano related. It could be Free iPhone or something like that.
The site is growing about 100 unique hits per day… and right now it is about 1100 per day.
If I can get something that will give me an average of a penny per traffic, that would be nice.
