Ain’t No Mountain High Enough: Motown’s Great Duet of Devotion

By Dan Cohen · Published 2026-06-27

Ain’t No Mountain High Enough, written by the songwriting team of Nickolas Ashford and Valerie Simpson, first reached the world in 1967 as a duet between Marvin Gaye and Tammi Terrell — and it remains one of Motown’s purest expressions of joy. Its whole message is devotion without limits: no distance, no obstacle, nothing at all could keep one person from reaching the other.

The magic of the call-and-response

The duet form is the heart of it. Gaye and Terrell trade and overlap lines, each promising to come running, building a feeling of two people completely in sync. Their partnership was one of the most beloved in soul, and the warmth between the voices is audible — it sounds less like a performance than like a genuine pledge passed back and forth.

Joy shadowed by loss

The story carries real poignancy: Terrell’s life was cut tragically short by illness not long after these recordings, which lends the duets a bittersweet glow in hindsight. The song was later reimagined as a bigger, more dramatic solo number by Diana Ross in 1970 — but the original duet’s unguarded happiness is its own irreplaceable thing.

What it measures like

On our scale it’s bright, warm and uptempo — buoyant, propulsive soul built to lift rather than to ache. Full profile on its song page.
