"Generate an audio clip that captures the essence of a heartfelt and emotional song. The song is in the singer-songwriter genre and should feature acoustic guitar, piano, and strings. The mood should start as gentle and introspective and gradually build to a more uplifting and hopeful tone, reflecting the lyrics about letting go and embarking on a new journey in life. The scale should be in a major key, and the tempo should be moderate. The song should evolve from a solo acoustic guitar and vocal introduction to include a full band arrangement with drums, bass, and harmonious backing vocals in the chorus. The overall audio clip should last approximately 3 to 4 minutes and should follow the structure of a typical song with verses, choruses, and a bridge."
