wabetune, screen by screen.

00 Getting started

First opening

1. Before you start asks the reference A, the tuning system, the language, how notes are named, the instrument with its transposition and the tolerance. All of it can be changed later in Setup.
2. Use in this browser, or Install on your device where it is offered (a phone or tablet whose browser can install it, or an iPhone, where the app shows the steps in Safari's Share menu). Installed, the app has the whole screen and its own archive, and opened as the installed app the window has one button, Continue.
3. The browser asks for the microphone. Allow it. While it is open, the screen stays on. If it was refused, the chip under the map says so; tap it for the steps to turn it back on.
4. A short tour rings the main controls once. Setup › Account › Replay tour shows it again.

Always on screen

01 Play

The screen the app opens on. It listens as soon as the microphone is open: you can play and read the map without recording.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

1. Logo reloads the app.
2. Account: Sign in or your name.
3. Plan: Lite or Pro.
4. Played cell: colour and cents of that note.
5. Note being played: drawn larger, white edge, needle across it.
6. Tonic: brass outline, in every octave. Only under just intonation and Pythagorean.
7. Dimmed cell: under a tonic, a note outside the scale of the declared mode (in C major E♭, A♭ and B♭; in minor the scale takes the raised sixth and seventh too). It is still played and measured, against its target; the ♭2 and the tritone have none, and are measured against equal temperament.
8. Octave number of the cells around it, shown on octaves where something was played.
9. Instrument chip: instrument and transposition.
10. Intonation chip: reference A, system and tonic.
11. Mode chip: major or minor; a tap turns it over.
12. Intonation trace: deviation over the last four seconds, with the hertz and the cents at its top left.
13. Swap: intonation trace ↔ staff, bottom left.
14. Start session: records.
15. Spectrum: every note at once, chords included.
16. Row of places.

The map

One hexagon per note, seven across. The rows alternate naturals and black keys and climb in octaves from the bottom. The map moves by whole octaves to keep the one you are playing on screen. Notes are written as your instrument reads them: with a transposition set, the map shows the written note.

Hold a hexagon and the phone sounds its note, at the target of the declared system. Keep holding: after half a second that note fills with brass from the bottom, in every octave, and after one more second it flashes and is the tonic (or the key, under a temperament). Let go before it is full and nothing changes. Held on the tonic itself, it turns its name over where the other name is a key in that mode too (E♭ minor ↔ D♯ minor, D♭ major ↔ C♯ major); where it is not (D♯ major would need nine sharps), nothing fills. Not under equal temperament, which has no tonic, and not while recording.

• A note is the median of its readings, attack discarded. A cell is the average of the last three seconds played on that note, weighted by how long each was held. The report reads the whole session.
• Not recording: a cell keeps its colour 30 seconds after the note ends, then fades in 5.
• Recording: nothing fades until the session ends.
• Very short notes count only inside a fast passage: 200 ms or more always counts.

Messages under the map

One line at a time, in a chip between the map and the chips. The words lead to the cause; the × puts it away.

Recording a session

The report

Opens when a session ends, and from the list of sessions in Stats.

1 2 3 4 5 6 7 8 9

1. Date and time of the session.
2. Measured against: A, system, tonic, what stays fixed, transposition if any. Fresh from a session on Lite, the free sessions left (14/15 left).
3. Length, mm:ss.
4. Within N cents: pitches inside your tolerance / pitches played.
5. To improve: pitches beyond the tolerance.
6. AI report: the session in sentences, note by note and interval by interval, and the note to start from.
7. Replay: plays the recording back and redraws the map as it was at each moment. Only while the recording is in memory: until the next session or a reload. The recording is never stored.
8. Map of the session. Press a played cell, then press again to remove that note from the report.
9. Intervals, then Notes: see below.

Intervals

F4 → G4	Two notes in the order played, octave included.
2 maj. asc.	Interval name and direction.
1× box	Times the pair was played. Press: every time, with how far into the session (in Stats, the date and hour).
Strokes	Where the two notes sit in tune. Lower note on the left.
Dots	The notes as played: first, second. Triangles point the way the interval went.
Figures	Cents of each note: green inside the tolerance, red beyond.
Bar length	Longer than the strokes: wide. Shorter: narrow.

Notes

Note ▲ ▼	Notes beyond the tolerance. ▲ runs sharp, ▼ runs flat, in the map's colour.
2× box	Times played.
Off by	Median of every attempt, in cents.
Swing	How much it varies from one attempt to the next. At equal deviation, the harder one to fix.

• Order: what weighs most first, how far beyond the tolerance times how many times.
• Five rows show; the ••• under the list shows five more. The ⓘ beside a title explains the list.

Foot of the report

Spectrum

Every note sounding at once, for chords, double stops and ensembles. Opened by the Spectrum button beside the record button; the narrow map button beside it goes back. It does not record.

02 Stats

Every session kept, over a window of time you choose. The figures are the report's, gathered.

1 2 3 4 5 6 7 8 9 10 11 12 13

1. ‹ › step to the previous or next window.
2. The window on screen: a date, a week, a month.
3. Day · Week · Month: the window's size.
4. PDF: the window as a PDF, to the phone's share sheet. For your teacher.
5. Dashed line: your tolerance.
6. Line and dots: mean deviation in cents.
7. Bars: time played, in minutes.
8. Totals: sessions, time, mean deviation.
9. Count box, green edge: press to open every time the pair was played.

12. •••: five more rows.
13. Sessions out: in how many of the sessions that had the note it came out beyond the tolerance (11/12).

Lists

Intervals	Pairs whose median is beyond the tolerance and most of whose times went the same way.
Notes	Notes that came back often and were off the same way most times. Columns: times, off by, swing, sessions out.
One list per system	Sessions under different systems or keys are never averaged together. A title separates them when there is more than one.

Sessions

› + date	Opens that session's report.
Length · Notes	Duration and notes kept.
±6¢	Pitches within the tolerance / pitches played.
To improve	The worst note and its deviation.

• With no sessions yet, Stats shows a drawn example, marked as such.
• The PDF keeps one table per system, tonic, A and transposition; sessions measured otherwise are counted, not averaged in.

03 Tuner

One cell of the map, large and alone, and a metronome under it.

1 2 3 4 5 6 7 8 9 10 11 12 13

1. The cell: same colours and tolerance as the map. Play a note when silent.
2. Needle: centre in tune, up sharp, down flat. Full height ±50 cents.
3. Note and octave.
4. Cents from the target of the declared system.
5. Hertz as heard.
6. Swap: hexagon ↔ intonation trace, bottom left. The Tuner opens on the trace; the device remembers the choice.
7. Intonation chip: opens Intonation.
8. Tempo, 40 to 208: − / +, or press the figure and type it. On a phone the app's own pad comes up from the foot and covers nothing that moves: ✓ sets it, a press outside leaves it.
9. Beats in the bar, 1 to 12.
10. Subdivision: opens the sheet of figures.
11. Beat bars: one per beat. Press: accented → on → silent.
12. Start / Stop.
13. Tap the tempo: tap in time to set it.

The Tuner opens on the intonation trace of Play, the whole width of the screen: the same line, dashes and letter, at ±50 cents, a line every 10, and the hertz beside the sign. Press the trace or the sign for the hexagon above.

The metronome

• 27 figures fill the beat, those without rests first. A rest is counted, not clicked.
• An accented beat always sounds, even when the figure starts with a rest. A silent beat is silent with its subdivisions.
• It keeps running when you leave the Tuner, with a lamp on the row of places. It runs through a recorded session; its clicks fall where the app is not listening.
• Volume: the phone's buttons.
• The device remembers the figure. Tempo, beats and marks start fresh each time.

04 Setup

One screen, six numbered sections. The chips on Play and Tuner open the same sections in a window.

01 Account

Google · Email	Two ways into the same account. Email sends a six-digit code to type here. Signed in, your sessions sync to every device.
Disconnect	Syncs; if everything reached the server, empties this device's archive.
Language	English, Italiano, Español, Français, Português, 中文, 日本語. Reloads the page.
Note names	C D E or do re mi. Reloads the page.
Install wabetune	When the browser allows it.
Replay tour	Shows the tour again.

02 Instrument

Instrument	Sets the clef of the staff. Choosing one fills in its transposition.
Transposition	What a written C sounds, B♭ (−2). Change it by hand for a part in another key (an A part on a B♭ clarinet).

03 Intonation

A	Reference pitch in hertz, typed (on a phone, on the app's own pad, 390 to 460). Changing it clears the map: what came before was measured against another A.
Temperament	Eight systems in two families (list). ⓘ: construction, period, when to choose it.
Major · Minor	Every system but equal. In just intonation it moves the ♭7; elsewhere only how notes are written. The mode chip under the map does the same.
Reference	Under a system that is not equal, which note stays put: A 442 Hz keeps the A at its hertz, Tonic D keeps the tonic at its equal-tempered pitch. A brass line marks that key at its top.
Keyboard	One octave, the black keys in a row of their own over the white ones. On each key its name, its degree and, in the band at its foot, its cents from equal temperament: blue below, orange above. Press a key to make it the tonic. A key is written as the chosen mode writes it (D♭ in major, C♯ in minor); where the other name is a key too, press it again for that one (E♭ / D♯ minor).

The cents on the keys are a difference from a piano, not a verdict. Played at its own target, every note reads 0 on the map.

04 Tolerance level

Level	In tune within
Beginner	10 cents
Mid	8 cents
Intermediate	6 cents (default)
Advanced	4 cents
King	2 cents

It moves the colours, the lists and the trace's band. Not what is measured.

05 Diagnostics

Folded. Press the title to open it.

Figures	Live: level, peak, gate and room noise in dBFS, pitch and clarity, gain, device, format, browser filters, audio state, build. A screenshot of this is what support asks for.
Test the measurement	Two presses: volume up, phone on a table, then 15 seconds of clicks and tones measured by the phone itself. Result: consistent or not, and a code (D-7DPSED) to quote when you write to us. No sound, device name or address is sent.

06 Write to us

Bug · Idea · Other	What the message is.
Message	Up to 4000 characters. The draft stays on the phone until it is sent.
Address	Optional. Without one, no answer.
Details	Browser, build and settings, on by default. A self-test from the same visit goes with it.

No account needed.

The chips' window

Pressing a chip on Play or Tuner opens its section of Setup in a window over the screen you are on. The controls are the same ones; a change there is a change in Setup. Close with ×, the backdrop or Back.
