BaritoneA baritone is a type of classical male singing voice whose vocal range lies between the bass and the tenor voice-types. The term originates from the Greek βαρύτονος (barýtonos), meaning "heavy sounding". Composers typically write music for this voice in the range from the second F below middle C to the F above middle C (i.e. F2–F4) in choral music, and from the second G below middle C to the G above middle C (G2 to G4) in operatic music, but the range can extend at either end.
OvertoneAn overtone is any resonant frequency above the fundamental frequency of a sound. (An overtone may or may not be a harmonic) In other words, overtones are all pitches higher than the lowest pitch within an individual sound; the fundamental is the lowest pitch. While the fundamental is usually heard most prominently, overtones are actually present in any pitch except a true sine wave. The relative volume or amplitude of various overtone partials is one of the key identifying features of timbre, or the individual characteristic of a sound.
Leslie speakerThe Leslie speaker is a combined amplifier and loudspeaker that projects the signal from an electric or electronic instrument and modifies the sound by rotating a baffle chamber ("drum") in front of the loudspeakers. A similar effect is provided by a rotating system of horns in front of the treble driver. It is most commonly associated with the Hammond organ, though it was later used for the electric guitar and other instruments. A typical Leslie speaker contains an amplifier, a treble horn and a bass speaker—though specific components depend upon the model.
BebopBebop or bop is a style of jazz developed in the early-to-mid-1940s in the United States. The style features compositions characterized by a fast tempo (usually exceeding 200 bpm), complex chord progressions with rapid chord changes and numerous changes of key, instrumental virtuosity, and improvisation based on a combination of harmonic structure, the use of scales and occasional references to the melody.
Double bassThe double bass (ˈdʌbəl_beɪs), also known simply as the bass (beɪs), amongst other names, is the largest and, therefore, lowest-pitched chordophone in the modern symphony orchestra (excluding unorthodox additions such as the octobass). Similar in structure to the cello, it has four, although occasionally five, strings. The bass is a standard member of the orchestra's string section, along with violins, viola, and cello, as well as the concert band, and is featured in concertos, solo, and chamber music in Western classical music.
Effects unitAn effects unit or effects pedal is an electronic device that alters the sound of a musical instrument or other audio source through audio signal processing. Common sound effects include distortion/overdrive, often used with electric guitar in electric blues and rock music; dynamic effects such as volume pedals and compressors, which affect loudness; filters such as wah-wah pedals and graphic equalizers, which modify frequency ranges; modulation effects, such as chorus, flangers and phasers; pitch effects such as pitch shifters; and time effects, such as reverb and delay, which create echoing sounds and emulate the sound of different spaces.
GlissandoIn music, a glissando (ɡlisˈsando; plural: glissandi, abbreviated gliss.) is a glide from one pitch to another (). It is an Italianized musical term derived from the French glisser, "to glide". In some contexts, it is equivalent to portamento, which is a continuous, seamless glide between notes. In other contexts, it refers to discrete, stepped glides across notes, such as on a piano.
