Lee Ritenour | Is It You?

Described by AllMusic as a “flawless musical chameleon,” Grammy-winning guitarist Lee Ritenour has collaborated as a session musician with artists from Pink Floyd to Quincy Jones to Dizzy Gillespie as well as releasing many of his own albums. His pop/jazz hybrid release “Is It You” (1981) reached number 15 on both the U.S. Billboard Hot 100 and Adult Contemporary charts.

There’s a classic direct modulation at 3:17, but the bridge (2:23 – 2:53) is perhaps more interesting, pivoting all over the place harmonically.

Arturo Sandoval | Emily

The all-too-often overlooked jazz standard “Emily” (Johnny Mandel and Johnny Mercer) has been covered by many greats, from Sinatra to Tony Bennett — and here by trumpeter Arturo Sandoval. The tune was the title song for the 1964 movie The Americanization of Emily. This arrangement features a lovely intro through 0:19; the form begins in earnest in C major before briefly touching on a key-of-the-moment (A major) for a few bars (0:39 – 0:48), then reverting to C.

Jerome Kern | The Way You Look Tonight

“The Way You Look Tonight,” co-written by Jerome Kern and winner of the Oscar Awards for Best Original Song in 1936 for its appearance in the movie “Swing Time,” was first performed by that film’s star, renowned dancer Fred Astaire. Multiple singers have covered this standard in the years since, from Ella to Billie to Sinatra to Tony Bennett, who is featured here. Modulation at the beginning of the middle section at 1:36, then back to the original key at 2:17.

US3 | The Love of My Life

Us3, a hiphop group with members from both the US and UK, is probably best known for the sample-heavy 90s hit “Cantaloop/Flip Fantasia.”

Like most of Us3’s output, “The Love of My Life” (2009) draws heavily on dense jazz-infused textures and chord progressions. But the sound is also driven by Hiphop grooves and lyrical traditions. The tune modulates up two whole steps at 0:38, pivoting between these two keys throughout: 0:56, 2:30, and 2:49.
