namm oddities 08

Tuesday, February 5th, 2008

here . A collection of strange instruments and other sightings at winter NAMM show. This years top oddity is the square drum. Browsing through the past years is interesting as well.

side remark: when I still was a student I attended (but didn’t really understand) a talk at a global analysis conference that addressed the question wether two different (shaped) drums can sound the same (can you hear the shape of a drum), that is wether there are different 2dimensional shapes that have exactly the same modes of resonance, so that you could not tell them apart by just listening to them (or looking at their spectra). It turns out there are (but the shapes do not look drum like at all…)
