the sound a liquidmetal musical instrument would make would probably be quite unique
Yes, the sound would be quite unique, and perhaps unflattering for a musical instrument that utilizes the acoustic properties in the metal to help shape the timbre of the sound. I have a Bachelors Degree in Instrumental Music (with emphasis on trumpet--right Watts?), aaaaand
I play the complete set of Liquidmetal golf clubs, and I can tell you first hand that the audible impact frequency of the driver is much lower than that of stainless steel or titanium. In fact, it's more of a thud-like sound.
Although this didn't add much to a discussion that wasn't going anywhere anyway, I had a few minutes of time to spare.
