This is my attempt to create a music block based player for the intro to Crazy Train by Ozzy. This plays the intro of the song.

A few of the needed notes were below the range of the minecraft block so I had to shift them up an octave which is close but doesn't sound perfect.

Also included are the plans that I used in case you need to modify it in any way.

Update: I finally added a video. Sorry about the background sounds.

Enjoy.
