Scat singing

In vocal jazz, scat singing is vocal improvisation with wordless vocables, nonsense syllables or without words at all. Scat singing is a difficult technique that requires singers with the ability to sing improvised melodies and rhythms using the voice as an instrument rather than a speaking medium.

Characteristics

Structure and syllable choice

Though scat singing is improvised, the melodic lines are often variations on scale and arpeggio fragments, stock patterns and riffs, as is the case with instrumental improvisers. As well, scatting usually incorporates musical structure. All of Ella Fitzgerald's scat performances of "How High the Moon", for instance, use the same tempo, begin with a chorus of a straight reading of the lyric, move to a "specialty chorus" introducing the scat chorus, and then the scat itself.Will Friedwald has compared Ella Fitzgerald to Chuck Jones directing his Roadrunner cartoon—each uses predetermined formulas in innovative ways.

The deliberate choice of scat syllables also is a key element in vocal jazz improvisation. Syllable choice influences the pitch articulation, coloration, and resonance of the performance. Syllable choice also differentiated jazz singers' personal styles: Betty Carter was inclined to use sounds like "louie-ooie-la-la-la" (soft-tongued sounds or liquids) while Sarah Vaughan would prefer "shoo-doo-shoo-bee-ooo-bee" (fricatives, plosives, and open vowels). The choice of scat syllables can also be used to reflect the sounds of different instruments. The comparison of the scatting styles of Ella Fitzgerald and Sarah Vaughan reveals that Fitzgerald's improvisation mimics the sounds of swing-era big bands with which she performed, while Vaughan's mimics that of her accompanying bop-era small combos.

Ella Fitzgerald

Ella Jane Fitzgerald (April 25, 1917 – June 15, 1996) was an American jazz singer often referred to as the First Lady of Song, Queen of Jazz and Lady Ella. She was noted for her purity of tone, impeccable diction, phrasing and intonation, and a "horn-like" improvisational ability, particularly in her scat singing.

After tumultuous teenage years, Fitzgerald found stability in musical success with the Chick Webb Orchestra, performing across the country, but most often associated with the Savoy Ballroom in Harlem. Fitzgerald's rendition of the nursery rhyme "A-Tisket, A-Tasket" helped boost both her and Webb to national fame. Taking over the band after Webb died, Fitzgerald left it behind in 1942 to start a solo career that would last essentially the rest of her life.

Signed with manager and Savoy co-founder Moe Gale from early in her career, she eventually gave managerial control for her performance and recording career to Norman Granz, who built up the label Verve Records based in part on Fitzgerald's vocal abilities. With Verve she recorded some of her more widely noted works, particularly her interpretation of the Great American Songbook.
