Key Names for Transposition

Major: Cb, Gb, Db, Ab, Eb, Bb, F, C, G, D, A, E, B, F#, C# Minor: Ab, Eb, Bb, F, C, G, D, A, E, B, F#, C#, G#, D#, A#

Agent Guidance

• Always use --json flag for machine-readable output
• Verify exports with export verify after rendering
• Use media probe to inspect an unknown score before operating on it
• Transposition requires both -i (input) and -o (output)
• Part names are case-insensitive for parts extract
