A minor scale that keeps one window open to the light.
The Mode
Dorian is the second mode of the major scale, start on the second degree and run to its octave. Built on C, it borrows its notes from B♭ major, giving a minor-sounding scale with a flattened third and seventh but, crucially, a natural sixth left intact. That single unflattened note is what separates Dorian from the plainer natural minor.
The result is a mode that is unmistakably minor in temperament yet refuses to be gloomy. It has a wistful, hopeful quality, melancholy with the collar turned up against the cold, a sadness that still looks outward. Among the minor modes it is the most balanced and the most cool-headed.

Character
Everything in Dorian turns on that natural sixth. In a minor context the ear expects the sixth to be lowered, so hearing it raised lends a lift, a splash of brightness against the minor third’s shadow. It keeps the mode from settling into pure sorrow, producing instead something poised and bittersweet, sophisticated rather than mournful. Symmetry helps too: the scale reads the same forwards and backwards, which gives it an even, self-contained balance.
In Practice
Dorian is the workhorse of modal jazz, funk, and rock, think extended vamps that stay on one minor chord and let the natural sixth glow. It colours a great deal of Celtic and English folk song, medieval church music, and countless minor-key grooves that need to breathe rather than mourn. It is arguably the most-used mode after the two that define major and minor themselves.
