What musical elements can I transpose?

You can transpose individual notes, chords (including complex qualities like maj7), scales, and entire progressions using the `transpose_element` or `transpose_progression` tools.

How does it handle transposing instruments?

The `apply_instrument_notation` tool automatically calculates the correct written notation for Bb (e.g., Trumpet), Eb (e.g., Alto Sax), and F (e.g., French Horn) instruments based on a provided concert pitch.

Can it resolve enharmonic duplicates?

Yes. By using `resolve_enharmonic_spelling`, you can provide a scale context (like 'G Major') to ensure that notes like A# are correctly spelled as Bb for better musical readability.
