APRES BASCHET AIR

APRES BASCHET AIR

This instrument has thirteen tuned large-diameter tubular air resonators. Each is capped at one end, and extending from the end-cap is a glass rod. The instrument is played by stroking the glass rods with moistened fingers to set up the vibration in the end-cap and, through it, in the air resonator. For this to work, the end-cap-and-glass-rod assembly must be tuned by a combination of weighting and thinning of the cap to bring its natural frequency into alignment with that of the conjoined air resonance tube, so that both of them are in agreement at the desired pitch. That done, it speaks readily with a full and warm tone — I just love the sort of big slow hooty elephant voice it has. The instrument has some problems, though: the tuning is unstable (as can be heard in this sound clip), and the glass rods break awfully easily.
