author
A name that appeared on generations of mail-order music books, this was less a single author than a long-running correspondence-school imprint built to teach practical playing at home. Its courses promised structured, step-by-step lessons for students working on their own, especially in piano and guitar.

by U.S. School of Music
U.S. School of Music appears on many vintage instructional books and home-study courses rather than on a conventional author biography. Listings for surviving editions show the name attached to piano and guitar lesson series issued across the mid-20th century, including multi-part correspondence courses designed for independent study at home.
From the available sources, it seems best understood as an educational brand or institutional byline instead of one identifiable writer. The books were packaged as progressive lessons, often numbered in sets, suggesting a practical course system meant to guide learners over time.
Because reliable biographical information about a specific person behind the name is hard to confirm, it is safer to treat U.S. School of Music as the credited teaching organization for these materials. That older, course-based identity is also part of the charm: these books come from an era when music lessons could arrive by mail and be worked through one lesson at a time.
