Tools
| Tool | Description | Behaviour |
|---|---|---|
| analyze_horn_harmonic_series | Analyze the natural harmonic overtone series (partials 2 through 16) for any F-horn or Bb-horn valve combination, returning equal-temperament cent deviations (e.g. -14 cents on 5th partial, -31 cents on 7th partial) and alternate valve solutions. | Read-only |
| diagnose_horn_intonation_and_hand_position | Diagnose pitch tendencies, right-hand bell acoustics, and Stopped Horn (gestopft / +) transposition rules (transpose down a half-step on the F horn side to compensate for the +1/2 step acoustic shortening when sealing the bell). | Read-only |
| generate_daily_horn_warmup_routine | Generate a structured daily French Horn warm-up schedule covering harmonic lip slurs, Farkas long tones, double/triple tonguing, low-register pedal tones, and dynamic control tailored to available practice time. | Read-only |
| get_orchestral_horn_excerpt_guide | Retrieve audition preparation notes, recommended F/Bb trigger fingerings, breathing plans, and historical crook transpositions for standard orchestral French Horn excerpts (Mozart 4, Beethoven 3/7/9, Brahms 1/3, Mahler 5, Strauss Till Eulenspiegel / Ein Heldenleben, Tchaikovsky 5). | Read-only |
| lookup_french_horn_fingering | Look up standard F-side and Bb-trigger valve fingerings, concert pitch transposition (down a perfect fifth), and harmonic tendency notes for any written French Horn note (e.g. "C4", "F4", "G4", "Bb4", "C5", "F5"). | Read-only |
| lookup_horn_trill_fingering | Find optimal whole-tone and half-step trill fingerings on the F/Bb double horn, identifying whether a trill should be executed as a mechanical valve trill or a harmonic lip trill (common above written E5 on the F side). | Read-only |
| recommend_beginner_horn_and_mouthpiece | Compare Kruspe wrap (Conn 8D style, dark orchestral projection, larger bell throat) vs Geyer/Knopf wrap (Yamaha 667/671, Alexander 103 style, smooth slurs, medium throat) and recommend mouthpiece cup depths and rim diameters by player level. | Read-only |
| transpose_french_horn_pitch | Transpose written French Horn parts from historical orchestral crooks (Horn in Eb, D, C, G, A, E, Bb-alto, Bb-basso) to modern Horn in F written pitch and Concert Pitch, with interval semitone shifts and clef rules. | Read-only |
