The Art of the Jazz Standard
"Ain't Misbehavin'" was composed by Fats Waller, but Louis Armstrong made it legendary with his unique vocal texture and rhythmic freedom. Unlike modern pop songs where precision to the grid is key, this song requires you to be "loose" with your timing while maintaining perfect internal rhythm.
To sing this well, you need to channel a relaxed confidence. The song is a declaration of fidelity, sung with a cheeky, knowing smile. It sits comfortably in the chest voice for most male singers, but the challenge lies in the "gravel" and the swing.
Phase 1: The A Section (Main Theme)
The opening line "No one to talk with, all by myself" sets the mood. Louis sings this with a bright, forward placement despite his deep tone.
The Trap: Dropping the energy at the end of phrases. Ensure you sustain the breath support through "all by myself" so the pitch doesn't sag flat.
Phase 2: The Bridge (B Section)
"Like Jack Horner, in the corner..." This section moves slightly higher and requires more punchy articulation. The lyrics are playful here. You want to emphasize the consonants (the 'k' in Jack, the 't' in talk) to drive the rhythm forward without speeding up the tempo.
Phase 3: The Scat Solo
Louis Armstrong invented modern scat singing. In many recordings, he abandons lyrics for rhythmic syllables ("Ba-ba-doo-day").
To master this, don't worry about pitch perfection as much as rhythmic conviction. Treat your voice like a trumpet. Use syllables that have percussive attacks to mimic the articulation of a brass instrument.
