Brystsstemme

Brystsstemme, known in English as chest voice, is a term used in voice pedagogy to describe the vocal quality and coordination typically associated with the lower part of the modal voice. In singing, it denotes the portion of the range where the voice feels strong and resonant in the chest, produced with relatively thicker vocal folds and higher subglottal pressure.

Physiologically, chest voice involves increased medial compression of the vocal folds and a heavier, more piston-like vibration pattern. The result is a fuller, louder tone with more emphasis on the lower frequencies. Resonance is often perceived as originating in the chest or torso, which gives the term its name, though resonance is shaped by vocal tract configuration and individual anatomy.

Range and transition: The chest voice generally covers the lower portion of the modal range, with exact limits varying between individuals. Many singers learn to access chest voice while also developing a controlled transition, or mix, to higher notes to avoid abrupt breaks at the passaggio.

Technique and training: Safe development emphasizes a relaxed larynx, diaphragmatic breathing, supported airflow, and gradual scale work. Exercises may include sustained vowels, scale slides, and gentle glides from chest voice upward toward mixed voice, while avoiding tension, forced phonation, or excessive breathiness.

Notes: The term is used across genres including classical, pop, and musical theatre, though pedagogical models differ. Some teachers describe vocal function rather than fixed ranges. Effective technique for brystsstemme aims for a balanced, non-strained voice with clear, efficient resonance.
