Record 30 seconds. Get scored.Most school orchestras and All-State auditions tune to A=440 Hz. Many professional and European orchestras use A=441 or A=442. If you are preparing for an audition, check your ensemble's standard. When in doubt, 440 is the safe default.
A drone is useful for long-tone practice, open-string resonance checks, and training your ear to a reference pitch before practicing. Playing along with a sustained drone at the correct concert A builds intonation awareness faster than playing without a reference.
Open string frequencies shift proportionally when the concert A changes. At A=441, every pitch is about 3.9 cents sharper than A=440. The drone here reflects that shift automatically when you switch between standards.
Orchestral bass is tuned in fourths: E1, A1, D2, G2. This is the standard orchestral tuning used at All-State and Regional auditions. Some soloists use a high-C extension string, which is not covered here. The drone covers the four standard orchestral strings.
