Whistling in the context of "Voice"

The human voice consists of sound made by a human being using the vocal tract, including talking, singing, laughing, crying, screaming, shouting, humming or yelling. The human voice is specifically a part of human sound production in which the vocal folds (vocal cords) are the primary sound source. (Other sound production mechanisms produced from the same general area of the body involve the production of unvoiced consonants, clicks, whistling and whispering.)

Generally speaking, the mechanism for generating the human voice can be subdivided into three parts; the lungs, the vocal folds within the larynx (voice box), and the articulators. The lungs, the "pump" must produce adequate airflow and air pressure to vibrate vocal folds. The vocal folds (vocal cords) then vibrate to use airflow from the lungs to create audible pulses that form the laryngeal sound source. The muscles of the larynx adjust the length and tension of the vocal folds to 'fine-tune' pitch and tone. The articulators (the parts of the vocal tract above the larynx consisting of tongue, palate, cheek, lips, etc.) articulate and filter the sound emanating from the larynx and to some degree can interact with the laryngeal airflow to strengthen or weaken it as a sound source.

Whistled speech is a form of speech surrogacy in which whistling is used to mimic speech. Speakers of more than 80 languages have been found to practice various degrees of whistled speech, most of them in rugged topography or dense forests, where movement to carry messages is challenging, and whistling expands the distance of communication. The practice is generally threatened by increased modernization and faster roads, but successful conservation efforts are recorded.

The Good, the Bad and the Ugly: Original Motion Picture Soundtrack was released in 1966 alongside the Western film The Good, the Bad and the Ugly, directed by Sergio Leone. The score is composed by frequent Leone collaborator Ennio Morricone, whose distinctive original compositions, containing gunfire, whistling, and yodeling permeate the film. The main theme, resembling the howling of a coyote, is a two-note melody that is a frequent motif, and is used for the three main characters, with a different instrument used for each one: flute for Blondie, arghilofono for Angel Eyes, and human voices for Tuco.

Among other elements, the score complements the film's American Civil War scenes, containing the mournful ballad "The Story of a Soldier", which is sung by prisoners as Tuco is being tortured by Angel Eyes. The film's famous climax, a three-way Mexican standoff, begins with the melody of "The Ecstasy of Gold" and is followed by "The Trio".

Jean-Baptiste Frédéric Isidor, Baron Thielemans (29 April 1922 – 22 August 2016), known professionally as Toots Thielemans ([tuts tiləmans]), was a Belgian jazz musician. He was mostly known for playing the chromatic harmonica, as well as his guitar and whistling skills, and composing. According to jazz historian Ted Gioia, his most important contribution was in "championing the humble harmonica", which Thielemans made into a "legitimate voice in jazz". He eventually became the "preeminent" jazz harmonica player.

His first professional performances were with Benny Goodman's band when they toured Europe in 1949 and 1950. He emigrated to the U.S. in 1951, becoming a citizen in 1957. From 1953 to 1959 he played with George Shearing, and then led his own groups on tours in the U.S. and Europe. In 1961 he recorded and performed live one of his own compositions, "Bluesette", which featured him playing guitar and whistling. In the 1970s and 1980s, he continued touring and recording, appearing with musicians such as Oscar Peterson, Elis Regina, Caetano Veloso, Ella Fitzgerald, Ivan Lins, Sarah Vaughan, Bill Evans, Dizzy Gillespie, Kenny Werner, Pat Metheny, Jaco Pastorius, Mina Mazzini, Elis Regina, Quincy Jones, George Shearing, Natalie Cole, Billy Joel, Paul Simon, and Paquito D'Rivera.
