FERNANDO VALENTI, one of the leading concert artists before the public today, is currently engaged in the monumental project of recording for Westminster the complete sonatas for harpsichord by Domenico Scarlatti. He inaugurated his career as a harpsichordist with a tour of South America in 1946, playing for audIences that had never heard this instrument before. He proved such a persuasive interpreter of the great keyboard literature of the 17th and 18th centuries-playing the authentic instrument-that these audiences demanded a repetition of the tour the following year. ValentI was the only harpsichordist invited to play at the now legendary Bach Festival in Prades, France. Later during the same summer (1950), he played and taught at the Institute for Humallistic Studies in Aspen, Colorado, where his performances were voted the most popular of the entire season. In the spring of 1951 he was appolnt’ed to the faculty of the Juilliard School of Muslc the first harpsIchord instuctor in the history of this institution.

TECHNICAL DATA
Play this recording only with an unworn, microgroove stylus,
preferably with a diamond tip. This recording is processed
according to the R.I.A.A. characteristic. Stereophonic equip·
ment enhances the sound of this monophonic recording,
making it richer and more brilliant. The original recording
was made on a one·track tape which was transferred without
further changes directly to a master disc. In this manner
the exact, original sound and the dynamic range were preserved
as they were heard and intended by the performing
artist in the recording hall. These pressings from the master
disc were compared with the original tape by the Westminster
music and engineering staff and only those pressings which
proved to be a comparable match were accepted for commercial distribution.
