The Dorian #4 scale, a variant of the traditional Dorian mode, introduces a raised fourth degree, giving it a distinctive and slightly exotic flavor. In terms of intervals, this scale can be expressed as 1, 2, ♭3, #4, 5, 6, ♭7. The raised fourth differences it from the natural Dorian, shifting its character subtly towards the Lydian mode but maintaining its minor essence due to the flat third and seventh. Useful in jazz and fusion for creating tension and interest over minor chords, the Dorian #4 scale provides a rich palette for both melodic and harmonic exploration. It sounds both familiar yet intriguingly novel, making it a valuable tool for guitarists seeking new creative horizons.
