Aprés Baschet sound sculpture created with parts scavenged from the collection of Barney Haynes.

In the winter of 2018, Baschetologist Marti Ruids came to San Francisco to put together an exhibition of aprés-Baschet instruments/sound sculptures at the Center for New Music. I had the great pleasure and fortune to work with him (and instrument builder extraordinaire Daniel Schmidt) building instruments for the exhibition. Daniel and I learned from Marti a great deal about the Baschets' philosophy and acoustic theories.
Many year later, helping the illustrious Barney Haynes to move shop I collected a few large metal pieces that seemed like they'd fall easily into the structure of a rodded aprés-Baschet sound sculpture, and they did! I only had to drill a few holes and notch creatively to create a stable structure (aka gum)
For the rods (aka oscillators) I used some stainless and some mild steel all-thread to develop my empirical intuition about the sonic differences of the different materials. The total length of the rods and nuts as weights on the ends of the rods were used to tune them into groups of complimentary pitches, all manipulated "found" tunings. I took Marti's technique of using colors to show pitch groupings that fit together (by my ear).
Two sheet-metal sound radiators (aka speakers) transmit the sounds to the air: the aluminium cone provides a 'woody' tone with most of the pitch information while the larger stainless speaker floating above the player's head gives reverb and high end shimmer.
