Invented by the Belgian Adolphe Sax in 1841 with the purpose of unifying the woodwind and the brass families. It is a single reed instrument made of brass in most cases. It is comprised of five parts: the Mouthpiece, the Chiver, the body, the keywork and the Bell.
The Sax usually has a powerful voice, projecting a loud sound, and thanks to these properties has became indispensable in the marching bands and it’s always present in the Jazz swing bands, appearing more and more often in contemporary music.
The sax family comprises the Sopranino Sax, the Soprano in Bb (straight and U shaped), the Contralto Sax in Eb, the Tenor sax in Bb, the Baritone sax in Eb, the Bass and Contrabass sax.
The most common types are:
The Soprano Sax can have straight or a U-shaped design (like the alto sax). Some manufacturers offer a slightly curved model, called "saxello", but typically the neck is curved toward the musician and the bell points upward, even rarer is the "Tipped Bell" sax, an instrument manufactured by Buescher around the 20’s and recently offered by popular brands, essentially shaped like the straight soprano, but the bell in the last 10-12 cm curves abruptly upward. The sound of the Soprano is typically nasal and thin.
The soprano Sax is a transposing instrument in Bb, with a note range from Bb 4 to F# 7 (actual notes from Ab to E)
Also known as Alto, offers the best compromise between dimensions and weight, a virtuoso’s instrument par excellence, agile and fast, with a quite loud voice. A principal instrument in Jazz and Bee Bop music, thanks to musicians who made it famous and popular like Charlie Parker, Ornette Coleman, Lee Konitz. Today we can find it often and often in the classic orchestra. You can hear a famous solo in the Ravel’s Bolero.
It’s the most representative member of the family, easily recognizable by the bent Chiver. Used mainly in military bands and orchestras both Jazz and classical, it’s a fundamental instrument in the sax quartets.
The tenor Sax is a transposing instrument in Bb, with a note range from Bb3 to F#6 (actual notes from Ab3 to E6)
It is the voice in the baritone register of the sax family, easily recognizable by its dimensions and the loop in the neck to reduce the height, making it more portable and playable. The modern Baritone sax has a longer bell with an added “low A” key. Used mainly in classical music and to some extent in Jazz music, it’s a fundamental instrument in the sax quartets. Widely used in marching bands in the baritone section, instead of or doubling the tuba part, offering a major rhythmical support to the musical composition.
The Baritone Sax is a transposing instrument in Eb, with a note range from Bb4 to F#7 (actual notes from Db3 to A5)
