Adagio for Strings — reimagined in Open B♭ Minor

Originally by Samuel Barber (1936, arranged from his String Quartet, Op. 11) Tuning used here Open B♭ Minor (a custom tuning built around the piece's own key) Key idea a suspension-chain built almost entirely on one recurring seventh chord that never lets the tonic settle

This is bowed string orchestra music, set to a plucked custom tuning — there's no guitar involved in the original at all, let alone a tuning to be faithful to. Rather than pick an arbitrary shape, this tuning was built specifically for the piece: it's Open A Minor, transposed up a half step so all six open strings ring out a bare B♭ minor triad — the piece's actual tonic — the moment you touch the guitar.

The Adagio is famous for almost never resolving: nearly every phrase is built on a chain of suspensions that lean into a minor iv7 chord and answer it with a V, again and again, without ever letting the tonic B♭ minor feel settled. The real fortissimo climax later in the piece doesn't reduce to a clean chord symbol in any source rigorous enough to trust, so it isn't included here — what follows is the well-documented harmonic skeleton of the opening chant-like phrase, and the famous unresolved ending.

Opening phrase

A minor seventh chord that keeps returning, never quite resolving

B♭m→ E♭m7→ F→ C₀7→ E♭m7→ D♭maj7→ A♭maj7→ E♭m7→ F

E♭m7 (iv7) is the real harmonic anchor of the opening — it recurs across the first ten bars, each time colored by a different chord (a plain V, a fully-diminished ii°7, a III7, a VII7) before it returns.

The opening phrase's harmonic skeleton, voiced in Open B♭ Minor, root in the bass throughout.

This is a structural reduction of a nine-voice string arrangement, not a lead sheet — no chord chart for this piece exists anywhere. Every chord shown is grounded in the piece's published harmonic analysis and verified against the app's own voicing engine in the real Open B♭ Minor tuning, with the true root in the bass throughout.
