In brass playing, what is meant by breath attack?

• A. The long sustain of a note.
• B. The articulation of a note by tonguing.
• C. The use of mutes to start notes.
• D. The initiation of tone produced by the first breath and air pressure at onset.

Answer: (D)

Breath attack is about the onset of the note—the moment the tone begins. In brass playing, the sound starts when you exhale and the lips begin to buzz with the right air pressure. A good breath attack means the note comes in quickly and cleanly from the first instant, with proper pitch and a solid core, thanks to steady air support and precise embouchure control. It’s different from how long a note sustains, how you articulate with the tongue, or using a mute to start notes. So the description that fits breath attack is the initiation of tone produced by the first breath and air pressure at onset.
