Regarding Glenn Gould's humming, I distinctly remember as a classical music neophyte when I purchased my first Glenn Gould recording. It was an album of the Kleine Preluden und Fughetten (sp!), and I had no idea what I was purchasing or who GG was. I took the album home, put it on and was mortified to hear singing, no less what seemed out of tune - like a piano record overdubbed on an old choral or singing record. I immediately marched the album back to the store and demanded a refund for the obviously defective album. Boy, did the sales clerks get a kick out of me. Since then I have come to overlook (overhear?) Gould's self-accompaniment and enjoy his artistry for what it is - always interesting, intellectually challenging, musically stimulating, and usually enjoyable. Joseph Previte
