Hindemith, Paul.

a fair-copy manuscript, notated in pencil on two three-stave systems per page, with autograph title, in ink, signed ("Paul Hindemith 1931...Spiel- und Hörschule"), inscription by Fried Lübbeckes to the upper right-hand corner of the title-page ("Emma zum Geburtstag 1931"), initial autograph designations ("Hohe Stimmen Mittlere Stimmen Tiefe Stimmen"), comprising five short pieces in all, 6 pages, plus blanks, oblong 4to (21 x 32cm), cut down from a larger, folio, leaf, no place, 1931; together with an autograph envelope and Christmas card by Emma Lübbecke-Job referring to the manuscript (3) 

These cleverly constructed wordless trios for three voices (high, medium and low) - five unnumbered short pieces of increasing harmonic subtlety - are a fine example of the composer's Gebrauchsmusik, and were presented by Hindemith to his friend the pianist Emma Lübbecke-Job on her birthday in 1931 (19 July).  A further number from "Spiel- und Hörschule" is known only from its publication in Pro musica: Organ für neue Musik, i (1932), pp.6ff.: see Paul Hindemith. Sämtliche Werke, Bd. VIII, 3 (2009), p.193. Some sketches for the work are preserved at the Hindemith-Institut, Frankfurt am Main.
