mature. The brass section in particular did not posses the ability to play chromatically (in all keys) until the advent of valves which allowed the length of the instrument to be changed while playing. This occurred around the middle to late 19th century. Consequently, the brass instruments are less prominent in the music of Bach, Mozart and Beethoven along with their contemporaries. Late 19th and early 20th century composers make use of a very large orchestra with all the fully developed wind instruments. Some of the master orchestrator/composers of this time were: Wagner, Rimskey-Korsakov, Ravel and Stravinsky. Currently, composers also make use of the full orchestra but with the addition of increasingly larger percussion sections which add many unique and unheard of sounds than in earlier music. Early Jazz music was played in small ensembles making use of clarinet, tuba, cornet, baritone, drums, and piano. Dixieland groups of New Orleans had similar instrumentation. During the Swing era, larger groups were employed to achieve more of an orchestral sound. The Big Bands of the this era were predominantly wind orchestras containing alto and tenor sax sections, trumpet and trombone sections, along with piano and drums. When Bop music arrived, the alto saxophone and trumpet were the preferred instruments of the major soloists who were backed up by piano, string bass and drums. With the advent ofFusion, electric instruments such as the electric guitar and keyboard synthesizer became prominent. How has each of these kinds of music been transmitted to later generations of musicians? Early in the evolution of classical music, a system of notation was gradually developed which for the most part remained stable from the Renaissance on. This gave the composer control over how his compositions were to be played. Throughout the history of Jazz, however, notation was more like a rough sketch. This was because the syncopated rhythms of rag...
