My partner is following his musical dreams and starting a mastering studio here in Portland, so to celebrate that and to inspire other musicians and music lovers, here is a musical roundup for everyone!  Make magazine's blog posts and points to tons of music projects for the tech-savvy, like this 1-Bit Groove Box by Noah Vawter, which is designed to be built by musicians:

Brian McNamara's project from issue 13 of the magazine is shared in the Make blog - the R-Tronic 8-Bit Toy Music Sequencer:



Make is way into theremins, and with a kit, you can make anything into a theremin!  Check out this video on making your room into a theremin, or these on theremin plants, or check out how the awesome Drawdio can turn almost anything into a theremin - see their instructables page for more details and lots more videos!



And for some non-techy music projects posted on Make, check out this video on how to make a willow whistle, or try making some awesome guitar picks!  (these are by flickr member Aud1073cH.)



Craft has some good music stuff too, like this awesome Rock 'N' Roll Speakers project!  (Originally in issue 7 of the magazine, you can see it now in the digital edition.)



And Craft shows us this amazing wearable toy piano - head over to instructables to see user mikamika's how-to!



And speaking of instructables - that site is a fabulous place to find all kinds of music projects!  For more techy-ness, check out pstretz's microcontroller fabric tone generator in C-code:



Geekboxjockey shows us how to make DIY electronic drums:



And jwilson27 made a pretty rad looking altoids tin guitar:



If you are like my guy and into recording music, check out belsey's instructable for building a music studio in an apartment building.



And now onto some projects for music listeners and non-techy crafters.... Scoochmaroo on instructables gives a how-to for these awesome monster speakers!



I knit up a cover for my iPod headphones like these by engrafted on craftster - easy and fun!



Thinking in magenta gives a free knitting pattern for iPod Earbud covers:



Stitch Lounge shows us how to make this simple iPod cord caddy:



Snow Blue on ravelry offers a free pattern for knit covers for bigger headphones that have lost their foam cushions.  If you're not a ravelry member, you can see the pattern here.



And if you prefer more attention-grabbing headphones, instructables user WurlitzerGirl shows us how to make these adorable stuffed animal headphones!



Of course there are tons of music-themed craft projects out there - I limited this roundup to usable music projects, that can be used to play or function in some way in listening to music.  Hope you enjoyed it, and be sure to add your favorite projects in the comments!  (By the way, that top photo was taken by me.)
