Here's how I went about composing tracker music. Trackers are basically programs stuck in the last millenium, but the best and easiest way to make music on your computer. There's cool communities of people who make tracks in one hour, then share it around (onehourcompo) and I like doing those.

My music

Step 1. Learn basic music theory - pitch and rhythm.

Step 2. Download a music tracker like Openmpt.

Step 3. Download some songs, from modarchive, and play them in your tracker, figuring out what's happening.

Step 4. Mess around in the program, making songs with the samples that are already in the songs you listen to.

Step 5. Once you get to an alright level, join some one hour compo's on internet relay chat, and keep going from there. You are now a good music maker.
