Gretchen Parlato’s voice is a cello. It’s a muted trumpet, a trombone. It’s an alto saxophone. It’s a small child crying out for her mother, a grown woman celebrating the pains of love. It’s a conflux where hope, sensuality, and tragedy all merge.
Parlato, 33, who won the 2004 Thelonious Monk International Jazz Vocals Competition and just released a beguiling album, “In a Dream,’’ is an ambitiously original singer with an understated approach. Her voice doesn’t rise much above a whisper, and she barely opens her mouth when she sings. She softly moans some lyrics, stretches out individual syllables for two and three bars, and adds wordless vocals that are more like sax solos than scat. More than that, she appears to see herself less as a singer than a musician whose instrument happens to be her voice. She is a fully integrated member of her band.
