Harmonics MusicLogo Design Contest

Harmonics Music is a Private musical instrument retailer operating both online and on the high street.

Open to colour choice. But I would like to see a narrow range used. Preferably two or three at a maximum. One is fine. Remember, this logo's primary function is to act as a shop sign and an internet banner) for website. However, it must also be appropriate for use on a letterhead, invoice, email, poster etc. It must be easily usable and recognizable.
Importantly, colours used must be transplantable to form corporate colours. ie they will be used for other applications.

VIBRANT BUT NOT JUVENILE.
GOOD COMBINATIONS MIGHT BE:

BLACK AND WHITE
BLACK AND ORANGE
SILVER

Just some suggestions...

See attached file for ideas. I like the idea of using a retro font. Perhaps like the lambretta font (60s chic) or perhaps a more traditional Art Deco font like Tw Cen MT. See tab 19 in the attached micorsoft publisher file. These were my own ideas but I'm not happy with any of them - need some professional assistance! Tab 9 is good but possibly, possibly, too modern for older musicians. I don't know. Tab 19 is also good but possibly, possibly, too old fashioned for younger musicians.

REMEBER - THIS LOGO NEEDS TO BE:
CLEAN, CLEAR AND CRISP!

MODERN BUT NOT IN ANY WAY JUVENILE.
