Freeware caution: always scan free downloads of anything for bugs and other threats before dumping the programs into your hard drive.
Get into your own groove by customizing one online with 8notes.com's Groove Generator
If you'd like to jam with other musicians online in real time for free, check out Jam Now.
The online music factory, Jam Studio, allows you to compose and play your original scores with a variety of instruments and beats (I actually wrote a song on this and it's extremely cool, and if I can do it you know it's easy enough for a toddler to use.) There's also what looks like a free recording program you can download and use to preserve your compositions.*
You no longer have to go to a bar to belt out your rendition of "I'll Survive", you can do it at home with KaraFun, "a free karaoke software for PC that offers a complete solution for home karaoke. Some of the player features are: Voice recording, Tempo and Pitch control, KFN, midi KAR, CDG+MP3 and LRC files replay, Direct 3D animation engine, playlist management, Fullscreen or windowed display, multi-monitor support."
MIDI to Wav Maker shareware "is an easy-to-use tool for converting MIDI to WAV format with CD quality."
Use this music code generator to get the HTML codes you need to add music to your web site, or this one for your MySpace page.
MyMusicTools.com has an entire page of music freeware here to help with your musical compositions.
This is one I really thought was neat -- the P22 Music Text Composition Generator turns your words into music played by your choice of instrument, music files and printable sheet music by allowing "any text to be converted into a musical composition. This composition is displayed in musical notation and simultaneously generated as a midi file." (Try this one when you have time -- it's the neatest online generator I've found since discovering Wordle.)
Wired has a good article here about creating music online with Hobnox Audiotool, a free virtual music studio.
Wolfram Tones is another free online music generator that uses music theory and algorithms to produce them. Just don't ask me to explain it.
