Quick Summary

Progressive tonality is a musical concept where a composition ends in a different key than it begins. This contrasts with traditional tonality, which centers around a single tonic note and key. Composers like Gustav Mahler and Carl Nielsen independently developed this idea in the late 19th and early 20th centuries, using it to create new forms and explore harmonic possibilities. This approach allows for a sense of journey and resolution as the music moves through various key regions before arriving at its final destination.123
