Enriched Output: K: Amin T: 75 TS: 4/4 INST: AcousticGuitar, ElectricGuitar, Bass, Drums, Strings, SynthPads Mood: Ethereal and introspective, building gradually to a hopeful and epic climax. Structure: Progressive/through-composed structure, building in sections (e.g., Intro -> Verse -> Build -> Climax/Solo -> Outro) **Summary:** The title "Stairs To Heaven" is a powerful and direct reference to the iconic Led Zeppelin song "Stairway to Heaven," which heavily influences this analysis. The musical style is inferred to be an epic rock ballad or a progressive rock piece that embarks on a sonic journey. The key of **A minor** is chosen as a direct nod to the famous arpeggiated intro of the reference track, providing a melancholic and mystical starting point. The tempo is set at a slow and deliberate **75 BPM**, allowing space for the arrangement to breathe and build gradually. A standard **4/4 time signature** provides a stable foundation for the track's progression. The instrumentation is designed to mirror the "stair-like" ascent implied by the title. It begins with a sparse, gentle **Acoustic Guitar**, creating an intimate and introspective feel. As the piece progresses, layers are added: lush **Synth Pads** and orchestral **Strings** provide an ethereal, heavenly atmosphere, while a solid **Bass** and **Drums** build the rhythmic intensity. Finally, an **Electric Guitar** enters, likely for a soaring and climactic solo, completing the journey from a quiet beginning to a powerful, epic conclusion. The structure is not a simple repeating pop format, but rather a progressive build that carries the listener through distinct emotional phases.
