Create a solemn friendship anthem in classic chanson style with march rhythms. Start subdued, then build intensity (crescendo) into choruses where lyrics are emphasized. Use acoustic guitar and piano with modern production — warm yet crisp. Male vocal: low timbre with raspy edge, delivered with heartfelt expression. Choruses should feel powerful and unifying, like a call to brotherhood. [Genre: Chanson] [Feel: Triumphal, heartfelt] [Instruments: Guitar, piano, light percussion] [Vocal: Male, low, gritty]
