A new classification of wind instruments: Orofacial considerations

Area of Science:

• Orofacial structures
• Biomechanics of wind instrument playing

Background:

• Wind instrument playing involves rhythmic jaw movements and specific embouchure forces impacting orofacial structures.
• Existing classifications may not fully capture the biomechanical nuances between instruments, particularly within the single-reed group.

Purpose of the Study:

• To propose an updated classification of wind instruments based on orofacial structures and embouchure mechanics.
• To differentiate between clarinet and saxophone player embouchures, despite their shared single-reed classification.

Main Methods:

• Lateral cephalograms were utilized to analyze the relationship between the mouthpiece and orofacial structures.
• The study included participants playing single-reed, double-reed, and brass instruments.

Main Results:

• Substantial differences were observed in the orofacial structures and embouchure mechanics across various wind instrument types.
• A new classification system is proposed, categorizing instruments by mouthpiece type and specific divisions (e.g., Class 1 single-reed: clarinet, saxophone).

Conclusions:

• Dental arches, teeth, and lips are crucial elements for a revised wind instrument nomenclature.
• The proposed classification emphasizes the relationship between the instrument's mouthpiece and neighboring orofacial structures, moving beyond traditional mouthpiece-based systems.
