A few selections later, the second bird-themed piece appears: “The Winter Wren Goes to 52nd Street.” This little bird has a complicated song, so much so that Winter had to slow down the tempo to crack its code. To his delight, he found a swing rhythm imbedded in the flurry of notes. When I later pulled up the recording on the Cornell’s Merlin app, I noticed how much the recording resembled musical notes. Winter spent hours transcribing the melody then wrote a piece in a slower tempo and made a medley with “Sweet Georgia Brown.” Does that tiny wren ever swing!
