Response is how readily the equipment/player combination produces sound. “Good” response generally means that the player-plus-instrument are able to produce a sound that starts precisely when intended, with clarity and with no unwanted additional noise. Many factors affect the quality and reliability of the response:
- Instrument condition. An instrument with leaks, cracks, problematic dents, etc. will often respond in a delayed or unpredictable way.
- Instrument quality. The instrument’s design and manufacture also play a role—an instrument of inferior design/build may respond inconsistently.
- Setup. Mouthpieces and reeds are similarly subject to design and manufacturing flaws, and must also be well-matched to each other and the instrument. A common issue with single-reed instruments, for example, is using a “strength” of reed that isn’t a good fit for the mouthpiece.
- Breath support. One of the most immediate and effective ways to improve response, even when other factors are less than ideal, is to use powerful, consistent breath support.
- Embouchure. Any embouchure problem can affect response, but by far the most common is embouchure tightness or tension. Remember that all woodwind embouchures should be relaxed.
- Voicing. This is one of the least-taught and least-understood, but one of the most crucial aspects of good woodwind playing. Properly-calibrated, steady voicing improves response (and just about everything else).
- Finger accuracy and timing. Fingers that arrive on their keys or toneholes out of sync, or that fail to form proper seals, impede response like the leaks that they are.
- Inherent acoustical problems. Even the best-made instruments have some built-in compromises that might make certain notes less responsive even under the best circumstances. A common example is the lowest notes on the flute, the oboe, and the saxophone, which may tend toward slight sluggishness even for the best players and equipment. Players may need to compensate in various ways.
- Musical context. Related to the acoustical problems of the various woodwinds, certain musical contexts may exacerbate issues. For example, the bassoon has some specific intervals that are hard to slur smoothly, and skilled bassoonists might use special fingerings to improve these.
For your best response on every note, be sure to address each of the many factors involved.
