1879-1888—London, England

Robert Hunter’s Encyclopaedic Dictionary, one of the most influential English dictionaries of its type during this era, mentions that the alto trombone is known as an E-flat instrument: “There are three kinds of trombones, called after their compass the alto, tenor, and bass trombones….The alto trombone has a compass of more than two octaves and a half, and is also known as the trombone in E-flat. It is written in the c clef, third line” (Hunter 215).
