Title: Soli I
Content:  Soli I was composed in March 1933 on a commission from the League of Composers, in celebration of their tenth anniversary. Chávez gave it the title Soli because in each of its four movements one of the instruments assumes a concertante role, playing a main part or "solo", but without relegating its companions to a secondary level of simple accompaniment.

Title: Solage

Title: Martial Solal
Content:  as a leader since 1953. Solal then began composing film music, eventually providing over 20 scores. He composed music for Jean-Luc Godard's debut feature film Breathless (À bout de souffle, 1960). In 1963, he made an appearance at the Newport Jazz Festival in Rhode Island; the Newport '63 album purporting to be a recording of this gig is actually a studio recreation with overdubbed applause, as documented in the sleeve notes of some later reissues. At this time, his trio included bassist Guy Pedersen and drummer Daniel Humair. From 1968, he performed and recorded with Lee Konitz in Europe and the U.S. In its January 2011 issue, The Gruppen Review published a 12-page interview in which Solal discusses his work as an eternal "researcher in jazz".
Title: Pierre Boulez
Content:  Griffiths observes that "Char's five poems speak in hard-edged surrealist imagery of an ecstatic sexual passion", which Boulez reflected in music "on the borders of fevered hysteria". In its original version (1946–47) the piece was scored for small forces (soprano, contralto, two ondes Martenot, piano and percussion). Forty years later Boulez arrived at the definitive version for soprano, mezzo-soprano, chorus and orchestra (1985–1989). Le Soleil des eaux (1948) originated in incidental music for a radio drama by Char. It went through three further versions before reaching its final form in 1965 as a piece for soprano, mixed chorus and orchestra. The first movement (Complainte du lézard amoureux) is a love song addressed by 
Title: Solvalou
Content:  The music and sound effects in Solvalou were composed by Hiroyuki Kawada, a Namco veteran that worked primarily on established franchises such as Galaxian and Valkyrie. Kawada was enamored by Xeviouss simplistic sine wave music cues, and wanted to incorporate this into the music for Solvalou. His familiarity with various forms of techno allowed him to further build on the kinds of sound effects in Xevious and "give them new colors". Kawada composed a hypnotic, minimal techno soundtrack that features remixes of Xevious music in addition to original pieces inspired by the original's world and aesthetic. Kawada used Namco's recently-acquired Apple and Digidesign sound tools to create the music, sampling music and sound effects from the sample editor program Alchemy and then programming it on a Macintosh computer. He produced hand-made sound effects with Turbosynth, a modular sequencer program, and created custom sound driver functions that could produce techno-inspired beats. These tools allowed Kawada to easily create music and sounds through single-line commands; Kawada said that "it was truly invaluable to be able to get a danceable groove with only a single command".

Title: Solitaire (Neil Sedaka song)
Content:  Sedaka originally was inspired by Frederic Chopin (his favorite classical composer) for the chorus and by Roberta Flack in the verses. When he presented the tune to Cody, he came up with the words based on his recent divorce; Cody had been playing solitaire frequently as a coping mechanism. Both Sedaka and Cody considered the composition to be a spiritual experience. Neil Sedaka recorded "Solitaire" as the title cut for a 1972 album recorded at Strawberry Studios, Stockport, England: 10cc members Lol Creme, Kevin Godley and Graham Gouldman accompanied Sedaka while Eric Stewart, also of 10cc, engineered the session. Appearing on 1972 album releases by both Tony Christie and Petula Clark, "Solitaire" had its first evident single release
