1897—London, England

Charles Vincent, whose Scoring for an Orchestra had been originally appeared in The Organist and Choirmaster, says, “There are three trombones in general use in a complete orchestra, viz.: the alto, tenor, and bass, though frequently the alto instrument is omitted, an additional tenor taking its place (Vincent 30). Regarding the key and range of the alto trombone, he says, “The alto trombone is in E-flat, and has a compass, for practical purposes, from [notated c to d-flat”]” (Vincent 31). And finally, he includes a position chart for alto trombone, saying, “The following are the notes produced from the seven positions on the alto trombone in E-flat [position chart for E-flat alto trombone] (Vincent 32).
