The Clarinet's Distinctive Tone
The clarinet is a single-reed woodwind with a cylindrical bore. Unlike a saxophone (conical bore) or flute (open pipe), the cylindrical bore of a clarinet produces only odd harmonics of the fundamental — giving it that unmistakable warm, hollow, woody tone. Our virtual clarinet replicates this with a square-wave oscillator (rich in odd harmonics) routed through a lowpass biquad filter tuned to roughly 4× the fundamental, softening the harsh upper harmonics into a mellow reed tone.
Transposition Note
The standard Bb clarinet is a transposing instrument — written C sounds as Bb one whole tone lower. Our online version is non-transposing for educational simplicity (notes sound at written pitch). When writing for a real clarinetist, transpose up a major second. Use our chord transposer to handle this automatically.
From Mozart to Benny Goodman
Mozart wrote the last concerto of his life for clarinet (K.622 in A), launching the instrument's serious repertoire. By the 20th century the clarinet became central to jazz via players like Benny Goodman, Artie Shaw, and Sidney Bechet. Today the Bb clarinet is the standard band and orchestral reed instrument.
