Irving Berlin’s How Deep Is the Ocean is one of the great American standards, combining a beautifully crafted melody with a harmonic structure that offers endless opportunities for exploration.

In this lesson, we take a close look at the tune’s abundance of minor ii–V progressions and how they shape the harmonic movement throughout the song. We’ll also examine one of the tune’s most distinctive moments: the unexpected move from I7 to iv7, a progression that briefly evokes the sound of the blues while adding emotional depth and color to the harmony.

Along the way, we’ll discuss practical approaches to improvisation, voice leading, and harmonic interpretation, all while staying connected to the melody that makes this standard so memorable.
