Mouthpieces

Isaac uses various appropriate mouthpieces depending on the instruments he is performing on. Whilst he generally believes in staying on one setup (especially on modern horn), using different mouthpieces for specific instruments contribute towards a performance practice that is not only historically informed, but the responses and feels of the mouthpieces also highlight the different responses, sounds and attentions needed for those instruments.

Below is an overview of the mouthpieces he uses, ranging from original to replicas of historical original mouthpieces.

**Baroque Horn Mouthpieces**:
L-R: Egger HBE 7 (primary mouthpiece); Franz Windhager Br/B3 Cup, M3 Rim
