Online Alto Flute Tuner
Alto flute in G sounds a perfect fourth below written pitch. Written C4 corresponds to G3, at 196 Hz with A4 = 440 Hz. This page opens with G transposition to show the note in your part without confusing it with the actual sounding pitch.
Written notes and concert pitch
Alto flute in G sounds a fourth lower: written C4 sounds G3, at 196 Hz with A4 = 440 Hz. The display shows written notes and actual frequency. Notes use scientific pitch notation: C4 is middle C and A4 the 440 Hz reference A.
| Written note | Concert pitch | Frequency (Hz) |
|---|---|---|
| C4 | G3 | 196.00 |
| D4 | A3 | 220.00 |
| E5 | B4 | 493.88 |
How to use it
- Warm up the alto flute for a few minutes and check assembly according to the maker.
- Enable the microphone, confirm G and choose the reference A agreed by your ensemble.
- Sustain a comfortable note without vibrato and read the display after the attack settles.
- Compare several registers; review air, embouchure and headjoint adjustments with your teacher.
Help and explanations
The frequency in Hz continues to describe the sound measured by the microphone. Warm up and choose your ensemble’s reference A before comparing notes. Use your usual playing position with either a straight or curved headjoint; fitting details depend on the model.
Written and concert notes on alto flute
Ordinary concert flute in C does not use the same transposition. On alto flute, written D4 sounds A3 at 220 Hz when A4 = 440 Hz. Establish whether the conductor requests a written or concert note before playing the reference; this display follows the written part.
Headjoint, tone production and stability
Keep your usual playing position so the air angle stays consistent between readings. Compare notes at similar dynamics, without trying to hold the needle still through extra tension. For assembly or headjoint-position changes, follow your maker and teacher rather than treating one isolated reading as a mechanical instruction.
Tips
- Keep the microphone away from direct breath and other instruments.
- Check again when the flute is fully warmed up.
- Test low and middle notes before judging the highest register.
Frequently asked questions
Is alto flute in G?
Yes, the alto flute covered here is in G and sounds a perfect fourth below written pitch. Ordinary flute in C uses a different setting.
Why does written C4 appear with 196 Hz?
Its actual sound is G3. G transposition makes the note display show C4, but Hz remain the frequency measured by the microphone.
Which written note produces concert A3?
Written D4 produces sounding A3. With A4 = 440 Hz, that sound has a frequency of 220 Hz. Check the octave before comparing with the ensemble.
Does the setting fit curved and straight headjoints?
The G transposition is the same, while assembly and posture may differ. Tune in your usual playing position and follow your model’s recommendations.
