E flat pitch, bore 11.95–12.45 mm (0.470"–0.490"), one-piece hand-hammered gold brass bell of 7.08" / 180 mm, conical brass outer slide with square slide crook, clear lacquered.
What does the Alto Sirius cost?
The base price is €3,100 (polished, incl. 19% VAT, as of April 2026) – making it the entry-level model in our trombone range.
How does an alto trombone differ from a tenor trombone?
The alto trombone is pitched in E flat and is built to smaller proportions. As a result it responds more easily in the high register and sounds slimmer and more brilliant – ideal for alto parts in Classical and Romantic orchestral literature.
