Online Baritone Sax Tuner (E♭)
The baritone saxophone is in E♭ and sounds an octave plus a major sixth below written: the C4 in your part sounds E♭2, 77.78 Hz. This page opens the chromatic tuner on E♭ + octave (baritone sax), which adds those 21 semitones back to the real sound, so the screen shows the note and the octave of your part.
Written note and concert pitch
The baritone sax tuner adds 21 semitones to the real sound to show the written note: C4 → E♭2 (77.78 Hz), with A4 = 440 Hz. The baritone sax is in E♭ and sounds an octave plus a major sixth below the part.
| Written note | Concert pitch | Frequency (Hz) |
|---|---|---|
| C4 | E♭2 | 77.78 |
| D4 | F2 | 87.31 |
| E4 | G2 | 98.00 |
| F4 | A♭2 | 103.83 |
| G4 | B♭2 | 116.54 |
| A4 | C3 | 130.81 |
| B4 | D3 | 146.83 |
How to use it
- Turn on the microphone and keep E♭ + octave selected.
- After warming up, hold written G4: it sounds concert B♭2.
- Push the mouthpiece in if the note is flat; pull it out if it is sharp.
- Test another note and check the octave reading on the low notes.
Help and explanations
In concert band, tune on written G, which is concert B♭: second-line G sounds 116.54 Hz. With an orchestra, use fifth-line F♯, which sounds the A at 220.00 Hz. Flat: push the mouthpiece onto the neck; sharp: pull it out. A bari has a lot of tubing to warm up: tune after a few minutes of playing, not right after assembling it.
E♭ + octave, E♭ or C?
Alto and baritone are both in E♭, but the baritone sounds an octave lower. E♭ + octave shows the full written pitch; plain E♭ gets the letter right but reads one octave too low. To compare with a piano or a tuba at concert pitch, select C (none).
Low notes on a phone
On baritones with a low A key, written A3 sounds C2, 65.41 Hz; without it, the lowest note is written B♭3, which sounds D♭2, 69.30 Hz. The tuner reads from 25 Hz up, but a phone mic picks up so little of that bass that the reading wobbles. To set the mouthpiece, use notes in the middle of the staff, and keep the low notes for checking your embouchure.
Tips
- If the reading wobbles, choose high (bass instrument) under Sensitivity and bring the phone closer to the bell, out of the air stream.
- Octave jumping on screen? The phone caught a harmonic of the low note; trust the note name and the cents.
- Changed reed or mouthpiece? Tune again: the right spot on the cork moves.
- Band tuning to 442 Hz? Change the Reference A; the transposition stays on E♭ + octave.
Frequently asked questions
What key is a baritone sax in?
E♭, like the alto sax: written C sounds E♭, an octave plus a major sixth lower. The C4 in your part is the piano's E♭2, 77.78 Hz.
Does the baritone sax read treble clef or bass clef?
The usual part is in treble clef, transposed in E♭ with the octave. To adapt a concert-pitch part, check both the transposition and the octave; changing only the clef does not guarantee the right pitches.
What is the difference between baritone sax and alto sax?
Both transpose in E♭ and share the same basic fingerings, but the baritone sounds an octave below the alto. Each one needs its own preset.
How do I tune a baritone sax?
Warm up, play written G (concert B♭) or F♯ (concert A) long and without vibrato and follow the arrow: up means push the mouthpiece in; down means pull it out. Stop when the number turns green and check one more note.
Is the baritone sax tuner free, and does it work online?
It is free and runs in the browser on a phone or computer, nothing to install. The sound is analyzed on your own device and is not recorded.
