Every composition in the Early Music series of Scholarly Brass Editions contains the source facsimiles, an Urtext edition (with notes and errata), and a minimally interpretive performing edition. Such should satisfy the widest possible range of needs. Our performing editions are of particular value for being notated at A4 = 440Hz. These works were composed during a period when A4 ≈ 466Hz on cornettos, trombones, and organs (i.e. a Baroque A = a current B-flat). Performing the original notation on an instrument conceived of as being at A440 would result in all sounding pitches being a semitone too low.
With this series, players can perform the composer’s original intent without having to learn new fingerings or slide positions. To clarify, playing a SBE performing edition part on a B-flat tenor trombone (A440) and playing the same Urtext edition part on an A tenor ‘sackbut’ (A466) will produce the same sounding frequencies. To further facilitate performance, when and where appropriate, supplemental parts are included in transposition and/or alternate clefs (e.g. E-flat alto trombone played using B-flat tenor trombone slide positions via notation a perfect fourth lower than sounding pitch and in tenor clef).
