NOTZART

1 Getting Started

Open Notzart. The Notes screen shows a music staff, a piano keyboard (or guitar fretboard), and in the header the ▶ autoplay and 🎙 mic buttons. Tap ▶ to begin a timed exercise, or tap → in the bottom-right corner to go at your own pace.

To move between screens, tap the ⌂ house in the top-left corner of any screen (see section 18).

On first launch, the app will ask for microphone permission — grant it to use the pitch-detection feature. You can still use the on-screen keyboard or fretboard without it.

2 The Exercise

A note appears on the staff. Your goal is to identify it and play or tap it correctly. There are three ways to answer:

• 🎙️ Microphone — play the note on your real instrument. Notzart detects the pitch live.
• 🎹 Piano keyboard — tap the correct key on screen.
• 🎸 Guitar fretboard — tap the correct fret/string combination.

After 3 wrong attempts, the note name and its position on the keyboard/fretboard are revealed to help you learn.

3 Microphone

Tap the 🎙 mic button to toggle listening on/off. When active, the app shows the detected note name and frequency in real time.

For best results, play a single, sustained note clearly. Chords or fast runs may confuse the pitch detector. The detector covers E1 (the low string of a bass guitar) up to C8 (the top key of a piano) and works the same on iPhone and Android.

Manual controls: Volume Threshold (how loud before the app listens) and Tone Clarity (how "pure" the pitch must be). The Instrument preset in Settings → Microphone → Instrument applies tuned defaults for each instrument:

• 🎹 Piano — Low / Soft / Stability 1 — picks up sustain quickly.
• 🎸 Guitar — Medium / Balanced / Stability 2 — handles plucked decay.
• 🎸 Bass — Medium / Balanced / Stability 2 — favours low fundamentals.
• 🎶 Flute — Low / Balanced / Stability 1 — clean tone, fast response.
• 🎻 Violin — Medium / Strict / Stability 3 — tolerates vibrato.
• 🎻 Cello — Medium / Balanced / Stability 3 — handles bowed swells.

4 Piano Keyboard

The on-screen piano shows the range around the current target note. Tap any key to submit your answer. White and black keys both work.

After 3 wrong attempts, the correct key is highlighted in light blue. If the microphone is on, the currently detected pitch is shown in cyan.

5 Guitar Fretboard

Switch to guitar view in Settings → Display → Instrument View → 🎸 Guitar. The fretboard shows standard tuning (E A D G B e) across 19 frets — the full classical guitar range.

• Strings are drawn top-to-bottom from high e to low E (as viewed from above).
• Tap any fret on any string to answer. A note can appear in multiple positions.
• Inlay dots appear at frets 3, 5, 7, 9, 12, 15, 17.
• Scroll horizontally to see higher positions.

6 Octave Selection

Go to Settings → Display → Practice Octaves. Tap the octave buttons (II · III · IV · V) to include or exclude them from exercises. At least one octave must always be selected.

Guitar range spans 4 octaves (II–V in Western notation = большая–вторая in Russian). Piano treble covers III–V, bass covers II–IV.

Scores reset when you close and reopen the app.

9 Tips for Best Results

10 Rhythm Notation

Enable rhythm features in Settings → Rhythm & Metronome. Once turned on, the staff shows notes with their correct rhythmic values alongside the pitch exercise.

Note durations: whole (𝅝), half (𝅗𝅥), quarter (♩), eighth (♪), 16th, and 32nd notes. Eighth notes and shorter are beamed together when two or more appear in a group.

Rests: when rests are enabled, a random slot in the note group may become a rest symbol. The app automatically advances past it after a short pause — no input needed.

Notation modifiers:

• Dot (·) — increases note value by 50%
• Double dot (··) — increases note value by 75%
• Tie (~) — connects two notes of the same pitch; the second is played as one held note
• Fermata (𝄐) — hold the note longer than its written value

11 Clef Guide

Select the clef in Settings → Display → Clef. Each clef uses a different set of notes and positions on the staff lines.

• 𝄞 Treble (G clef) — most common. Bottom line = E4, top line = F5. Used for piano (right hand), guitar (sounds an octave lower), violin, flute, and most soprano/alto instruments.
• 𝄢 Bass (F clef) — bottom line = G2, top line = A3. Used for piano (left hand), cello, bass guitar, tuba, and baritone voice. In the Songs Trainer the bass clef carries the left-hand line on stages 2, 4, 6 and the lower stave of stage 7.
• Alto (C clef) — middle line = C4 (middle C). Used primarily for viola. Helps avoid many ledger lines in the viola's typical range.
• Baritone (C clef) — top line = C4. Used for baritone voice and some brass parts. C4 sits high on the staff instead of in the middle.

12 Tuner

Open ⌂ → Tuner. The tuner works independently of any exercise and can be used at any time.

• Tap the mic button to start listening. The large note name, octave and frequency update in real time.
• The accuracy counter shows how close you are to the nearest note: 100 % is perfectly in tune, 0 % is a quarter-tone (50¢) away. 10¢ off reads 80 %, 25¢ reads 50 %. The number glides smoothly and fades to 0 in silence.
• The note name and the closest open string are colour-coded: green within ±15¢, yellow ±15–35¢, red beyond.
• A line drawing of the selected instrument sits on the left of the screen.
• Select the instrument tab to change references:
  • Guitar — 6 strings: E2 A2 D3 G3 B3 e4
  • Bass — 4 strings: E1 A1 D2 G2
  • Flute — A4 = 440 Hz reference tone
  • Violin — 4 strings: G3 D4 A4 E5
  • Cello — 4 strings: C2 G2 D3 A3

13 Violin · Cello · Bass · Flute

Select your instrument in Settings → Display → Instrument View. Each mode replaces the on-screen keyboard with the most useful representation for that family.

🎻 Violin / Cello — Intonation Indicator

Bowed instruments show an intonation light — a vertical bar showing how close your pitch is to the target note.

• ● Green — within ±15¢ of the target (in tune)
• ● Yellow — within ±35¢ (slightly out of tune)
• ● Red — more than ±35¢ off (significantly out of tune)

Violin range: G3–E5 (all four strings, G–D–A–E). Cello range: C2–A4 (all four strings, C–G–D–A).

🎸 Bass Guitar — 4-String Fretboard

Bass mode shows a thick-string fretboard in standard 4-string tuning: E1 A1 D2 G2. Notes are notated on the bass clef (the bass guitar sounds an octave lower than written, like a regular guitar). Octaves 1–4 are practiced by default.

Mic preset: minRms 0.005, clarity 0.55, stability 2 — tuned to capture the low fundamentals of a bass guitar without confusing harmonics.

🎶 Flute — Note Display + Fingering Chart

Flute mode replaces the keyboard with a big note name centered on screen, with all three name systems (C–D–E / До–Ре–Ми / Do–Re–Mi) shown below. A simplified Boehm-system fingering diagram appears under it: a horizontal flute body with 8 keys, the ones to press highlighted in blue.

Range: C4–C7 (concert flute). Octaves 4–6 are selected by default. The flute synth uses a clean sine wave with subtle 2nd-harmonic warmth, slow attack, and gentle 5 Hz vibrato — close to a real flute's timbre when played back.

14 Songs Trainer

Open ⌂ → Songs. Notzart ships with 39 melodies: 35 classic tunes across 6 keys — C major (Twinkle, Für Elise, Ode to Joy, Mary Had a Little Lamb…), A minor (Greensleeves, House of the Rising Sun), D minor (Hava Nagila, Scarborough Fair), E minor (Drunken Sailor), G major (Vincent, Silent Night, Edelweiss), D major (Oh Susanna, Camptown Races), F major (Auld Lang Syne, Brahms Lullaby, My Bonnie) — and four two-hand piano pieces read from printed scores: Comptine d'un autre été, Children, Passacaglia and A Time For Us.

The screen

The Songs screen has the same layout as Exercises: a slim toolbar, a thin progress bar, the staff filling the middle, and the piano keyboard at the bottom with the note to play lit up.

• 1–8 — the learning stages (below). The filled button is your stage; green-outlined ones are done.
• 🔊 — play the melody through the speaker. 🎙 — listen to your instrument. ↺ — start the stage over.
• − BPM + — tempo, 40–200.
• ≡ — the song list. N/M — notes played in this stage.
• Under the toolbar: song · stage · fragment on the left; ‹ Bar N/M › on the right, plus ▶ / ❚❚ on tempo stages.

Song list

Tap ≡ to open a book-style index. The current song is highlighted; your imported songs appear in italic. Tap a row to load it, long-press an imported song to delete it, or tap + to import a PDF (section 16).

The eight learning stages

1. 1. Right-hand fragments — the melody is split into 8-note chunks. Play each chunk at your own pace.
2. 2. Left-hand fragments — same approach for the bass line, on the bass clef.
3. 3. Full right hand — the entire melody, advancing as you play.
4. 4. Full left hand — the entire bass line.
5. 5. Right hand at tempo — the staff scrolls at the chosen BPM. Play along.
6. 6. Left hand at tempo — same for the bass.
7. 7. Both hands — two staves; the cursor moves on when you play the right note.
8. 8. Both hands at tempo — two staves, driven by the clock. After ▶ the clock waits for your first note.

When a stage is done, a card floats over the staff with your accuracy and a button to the next fragment or stage.

Notation

• Engraved look — tilted note heads, hollow half and whole notes, stems up below the middle line and down above it, level beams over groups of eighths and sixteenths, drawn flags.
• Sharps and flats drawn next to the note heads, bar lines and the song's own time signature.
• Beat-proportional spacing — both staves stay aligned beat for beat.
• 8va / 8vb — a bar that climbs far above (or below) the staff is drawn an octave nearer with an 8va (8vb) line, just like printed music. The keyboard and the microphone still use the real pitch.
• Always fits — the staff scales itself so every note is visible, however high or low the piece goes.

Feedback

On every detected note the progress bar flashes green (right pitch) or red (miss) and a large ✓ / ✗ appears. In manual stages a wrong note does not move the cursor; in tempo stages the clock keeps going and your accuracy reflects how well you matched each beat.

15 Exercises

Open ⌂ → Exercises. Sixteen short two-hand studies — from Five Fingers Together and Contrary Motion to Scale with Turn and Coordination Study — each on a grand staff: right hand on the treble clef, left hand on the bass clef.

• ‹ 1…6 › — exercise numbers, six at a time; the arrows page through the list.
• 🔊 — hear the exercise played through the speaker while the staff follows.
• 🎙 — play it yourself; the cursor advances on each correct note.
• The keyboard lights up the next note for each hand.

16 Importing Sheet Music

Add your own songs from PDF: ⌂ → Songs → ≡ → +, enter a title, and choose the file.

• Offline and private — the score is read on your device from the PDF's own drawing. Nothing is uploaded, no account or internet connection is needed.
• Checked bar by bar — after reading, Notzart tells you how many bars it found, the time signature, and whether every bar added up.
• At written pitch — notes keep their octave; far-off passages are shown with 8va / 8vb.
• Saved — imported songs stay in your library after you close the app. Long-press one in the list to delete it.

17 Stats & History

Open ⌂ → Statistics to see your top 8 best practice sessions. Each row shows:

• 🥇🥈🥉 — medals for the top 3 sessions; numbers 4–8 follow.
• Date — when the session ran.
• Accuracy % — color-coded: green ≥ 90, gold ≥ 70, red below.
• Pills — ✓ correct count · ✗ wrong count · 🔥 longest streak.

Sessions are saved automatically when you background or quit the app, provided you played at least 3 notes. Older sessions outside the top 8 are dropped to keep the list focused on your best work.

All data is stored locally on your device via AsyncStorage — nothing is uploaded.

18 Home Menu

There is no tab bar at the bottom — the whole height of the screen belongs to the staff and the keyboard. Instead, every screen has a ⌂ house button in its top-left corner. Tap it and the list of screens opens right under it:

• ♪ Notes — the single-note reading trainer with staff, keyboard or fretboard, metronome and autoplay.
• ✋ Exercises — two-hand studies (section 15).
• ♫ Songs — melodies, stages and PDF import (sections 14 and 16).
• Tuning fork — Tuner (section 12).
• ▮ Statistics — your best sessions (section 17).
• ⚙ Settings — language, clef, instrument, microphone, rhythm (section 7).
• 🚪 Exit — on Android, closes the app and switches the microphone off. On iPhone, leave the app with the usual home gesture.

The current screen is highlighted. Tap anywhere outside the list to close it. Screens keep their place while you switch — the song, stage and bar are where you left them.
