Why is tuning A used at the start of a wind concert?

• A. To establish a reference pitch for the ensemble's intonation.
• B. To warm up the lips.
• C. To calibrate the metronome.
• D. To check instrument humidity.

Answer: (A)

Tuning to A provides a single, stable reference pitch for the whole ensemble. A is the standard concert pitch (A4 around 440 Hz), so when the tuning note is set, every player has a common target for intonation. In wind sections, the oboe (or another reliable pitch source) usually starts with a sustained A because its tone and pitch stability give a clear, easily heard reference. Players then adjust their instruments until their pitch matches that A, bringing all sections into unison across the spectrum of notes. This alignment is essential for good blend and accuracy throughout the performance.

Warming up the lips, setting a metronome, or checking humidity aren’t the primary purpose of this moment; those tasks occur separately.
