Buffet R13 Bb Clarinet. Professional model. Flawless condition.

This auction is for a Buffet R13 Bb Professional Clarinet, serial number 131824, in flawless condition. It´s an instrument with an aura. It was acquired in 1978 from Phil Rehfeldt, Professor of Woodwinds and Musicology (a clarinet specialist and new music performer) at the University of Redlands in southern California. Since that time it´s been in the possession of Ron Pellegrino, composer and pioneer in the electronic arts of sound and light - http://www.ronpellegrinoselectronicartsproductions.org/

It´s been played lightly throughout the years primarily during the early 1980s and then the early 2000s in a three-year streak of 90-minute meditation exercises over the full frequency range of the instrument exploring classical tonal theoretical constructs and melodic structures.

The instrument´s servicing has been done by Daniel Deitch, tech artist to the top professionals in the San Francisco Bay Area and beyond, who works out of his Historical Woodwinds & Repair Workshop in San Francisco, CA. In a recent conversation Daniel informed me that he believed the instrument was built in 1972.

Comes with mouthpiece, ligature, cap, bore oil, cork grease, some Vic Olivieri reeds, and a Buffet leather case in excellent condition.
