I just returned from a Jim Coleman Sr. seminar where he showed us his tuning using pure 5ths. He tuned two S&S B's, one with a strict FAC tuning, one with his pure 5ths tuning. After playing 15 different short pieces ( Several different people played) on each piano, and varying the order that the pianos were played, the pure fifths piano received almost twice as many votes as the FAC tuned piano. It was very enlightening, and I hope Jim relates more of his results over time. Thanks to the Austin, TX chapter for a wonderful seminar and very pleasant experience. Tom Thompson, MPT Ft. Worth
