"Waltz for Debby" is a jazz standard composed by pianist Bill Evans. He recorded it as a solo piano piece on his album New Jazz Conceptions (1956). Lyrics were written by Gene Lees. "Debby" in the song title refers to Evans's niece, Debby Evans.
"Waltz for Debby" is known in Swedish by the name "Monicas Vals"; lyrics were written by Beppe Wolgers; and in Finnish by the name "Ankin Valssi"; lyrics were written by Jukka Kuoppamäki.
When pianist Milcho Leviev realized that the song is based on a Chopin etude, he reworked it on a Bulgarian time signature, and called it "For Fred and Bill in Time".
