That probably made it sound more sophisticated than it it is. I’m using Arduino and fooling around trying to make a musical instrument. I have accelerometer and gyroscope sensors and I’m trying to figure out the up vector and measure tilt while the player is moving it around.

Interesting.

This is probably overkill, but this is the most comprehensive treatment on the subject I've come across till date [1]. Note that the price on Amazon is ridiculous, the author has a very 90s looking website with a much more reasonable price. It has a very sketchy looking "enter credit card information here:" online store - I was nervous to buy from there, but I successfully got my copies, and the author emailed me to let me know he had personally dropped off the books at USPS :)
