Long tone exercises with live feedback
Long tone exercises mean sustaining one note while keeping its tone, pitch and airflow steady. This free tracker shows the pitch in cents, the relative microphone level and the longest stretch without a detected gap. It works with flute, trumpet, saxophone, trombone and clarinet, without recording or uploading your playing.
What does a long tone measure?
A long tone is one sustained note; this tracker measures pitch deviation in cents, relative input level in dBFS and uninterrupted detected time.
| Readout | Meaning |
|---|---|
| 0 cents | The selected concert-pitch target |
| + / − cents | Sharp / flat relative to that target |
| dBFS | Relative digital input level, not acoustic SPL |
| Sustained time | Longest stretch without a detected pitch gap |
How to use it
- Turn on the microphone and allow access. Keep the device at a consistent distance.
- Select A=440 or 442 Hz to match your ensemble. Displayed pitches are concert pitches.
- Choose an exact target note, or let the first stable note set the target automatically.
- Press Start practice. The timer begins when the tracker detects your first stable note.
- Hold the note for the selected time, then compare the pitch trace, input-level trace and longest uninterrupted tone.
Help and explanations
Use a comfortable middle-register note first. Choose a five- or ten-second practice window, play at a relaxed volume and listen as well as watch. A flat trace can help you notice a habit, but it cannot judge embouchure, resonance or musical expression. The goal is a controlled sound, with time to breathe between takes.
Long tone exercises for flute, trumpet and saxophone
For flute, try a middle-register note before moving through nearby notes. For trumpet, start with an easy note and a clear, gentle attack. On saxophone, compare the beginning and end of each take before adding a gradual crescendo. Clarinet and trombone players can use the same routine. Pick notes and dynamics with your teacher rather than copying another player’s range.
Reading pitch and volume
Zero cents is the selected target; positive values are sharp and negative values are flat. The pitch graph spans ±50 cents and the percentage counts detected samples within ±10 cents. This is a practice guide, not a universal passing grade. Relative level uses dBFS: microphone distance and automatic processing can change it, so compare takes with the same setup.
Written notes and concert pitch
The tracker shows sounding concert pitch. A written C on a B-flat trumpet or clarinet sounds B-flat; an alto saxophone uses E-flat transposition. Choose the sounding target, or use automatic detection. For ordinary tuning, open the chromatic tuner.
Tips
- Keep the device position fixed between takes.
- Rest for a breath or two after every sustained note.
- Begin without vibrato when comparing steady pitch, then practise musical vibrato separately.
- Practise gentle changes in dynamics while listening for tone quality, not only watching a line.
Frequently asked questions
Long tone exercises flute: where do I start?
Choose an easy middle-register note. Hold it comfortably, rest, then try a nearby note without changing the device position.
Long tone exercises trumpet: how long should I play?
Start with five or ten comfortable seconds. Stop before the sound or posture becomes strained, and rest between takes.
Long tone exercises alto sax: which note is shown?
The display shows concert pitch. Use automatic target detection if you want to follow the sounding note without converting from the written pitch.
Long tone exercises clarinet: why does the trace move?
Small changes in air or voicing can move pitch. Background sound and microphone processing can also affect the reading.
Long tone exercises trombone: can I use the timer?
Yes. The timer starts on a detected note, and the longest sustained time resets when detection is interrupted.
Long tone exercises for band: can I use 442 Hz?
Yes. Set the A reference to 442 Hz when that is your band’s chosen reference; follow your director’s tuning instruction.
