Sheet Music Display
![The Ultimate Piano sheet music display below the keyboard: C, E, G and A pressed, grand staff with the chord and the name C6 [I6] with the alternative Am7/C](https://the-ultimate-piano.com/wp-content/uploads/2026/10/sheet-music-display-2026-10-22.webp)
The sheet music display writes every note you play onto a grand staff, live, and names the chord above it. Mouse, touch or MIDI — The Ultimate Piano notates it as it happens. It is equally useful for checking yourself against a score and for connecting the notes on the page with the keys under your hands.
Score writes your playing in standard musical notation — the written language of music used worldwide.

How the Sheet Music Display Works
The sheet music display updates in real time with every note you play. As you press keys on the keyboard (mouse, touch, or MIDI), the staff redraws instantly and shows:
- Note positions – Each note appears at its correct position on the staff
- Accidentals – Sharps and flats are written the way the keys are named: after the chord you play, otherwise after the key selected in the header
- Chords – Multiple notes played together appear stacked vertically as a single chord
No conversion step and no recording is needed — the notation is live while you play.
Score Window Views
The small View menu in the top right corner of the score window switches between three views:
The menu changes the same settings as Show score and Show chord names in Settings → Display → Score & Chords, so both places always agree.
Grand Staff & Single Staff Options
The score renders on a grand staff by default, and you can switch to a single staff in Settings. The grand staff combines 2 staves — one treble and one bass clef — exactly like printed piano sheet music.
Grand Staff
The Grand Staff is on by default and shows treble and bass clefs together, just like piano sheet music. Notes from middle C (C4) upward sit on the upper (treble) staff, notes below middle C on the lower (bass) staff.
Single Staff
Turn off Grand staff (2 staves) in Settings → Display → Score & Chords to show a single staff. The clef then follows the notes you play:
- Treble Clef – Higher notes
- Bass Clef – Lower notes
Key Signature
The key signature sets how notes and chords are spelled on the staff. Click the Key button in the header (it shows the current key, for example "Key: C") to open the Circle of Fifths and pick a major key on the outer ring or a minor key on the inner ring. The score shows the matching key signature and respells accidentals to match it. 15 key signatures are available, from 7 flats to 7 sharps — covering all 12 major and all 12 minor keys.
How it affects note spelling:
- In C Major (no sharps or flats): the black key between F and G appears as F♯
- In F Major (one flat): the black key between A and B appears as B♭
Chord names follow the key as well: in C major the chord B♭–D–F is named Bb, not A#. This lets you read notes the way they would appear in actual sheet music for your chosen key.
Chord Detection
Chord detection names the chord you are playing above the staff in real time. With Show chord names on (the default), play 3 or more notes together and the sheet music display shows the chord name — for example "C", "Am", "Cmaj7" or "G7". Chord detection works with any input method: mouse, touch, or a connected MIDI keyboard.
The main name sits in the middle. Many chords can be read more than one way, so up to two alternative names appear smaller to its right — in narrow windows they move below it:
When the lowest note is not the root, the name is written as a slash chord (Am7/C = A minor seventh over C).
Chip colours: the background and text colour of the chord name can be changed in Settings → Display → Score & Chords. To give chords your own names, use My chord rules in the same place.
Intervals in the Chord Name
Turn on Show intervals in Settings → Display → Score & Chords (off by default) to add the chord's structure to the name. The intervals are listed in pitch order from the lowest note upward, which reveals the actual voicing of the chord:
C (3, 5)– C major in close position: 3rd and 5th above CC (5, 3)– C major in open position: the 5th lies below the 3rdCmaj7 (3, 5, 7)– C major 7th = major 3rd + perfect 5th + major 7thC9 (3, 5, ♭7, 9)– C dominant 9th
This visual breakdown helps you understand both chord construction and how different voicings are built.
Chord Degree
Set Show chord degree in Settings → Display → Score & Chords to show where the chord sits in the selected key, in square brackets after the name:
Chords outside the key get a degree too, so borrowed chords such as ♭VII are easy to spot.
Interval Detection
Interval detection names the distance between exactly 2 notes. When you play two notes, the display shows the lower note and the interval name above the staff — simple and compound intervals alike:
Within one octave:
C Perfect 5th– C and G (7 semitones)A Minor 3rd– A and C (3 semitones)F# Tritone– F♯ and C (6 semitones)C Octave– C and the next C
Beyond one octave:
C Major 9th– C and the D an octave higher (14 semitones)C Perfect 11th– 17 semitonesC Major 13th– 21 semitonesC Double Octave– two octaves apart, and beyond that for exampleC 2 Octaves + Perfect 5th
Interval detection helps you learn to recognize intervals by ear and to understand the building blocks of every chord.
Position Options
The sheet music display can sit in any of 4 positions around the keyboard, so it never covers the keys you need. Move the score window to your preferred location:
- Below the keyboard (default)
- Above the keyboard
- Left or Right side
Adjust the position in Settings → Display → Score & Chords → Position.

Frequently Asked Questions
Does the sheet music display work with mouse and touch input?
Yes. The sheet music display updates in real time with any input method — mouse, touch, or a MIDI keyboard. Every note you play appears instantly on the staff.
What is the difference between single staff and grand staff?
Single staff shows one clef that switches automatically based on the notes you play. Grand staff combines 2 staves — treble and bass clef together, split at middle C — like traditional piano sheet music, covering the full keyboard range.
How does chord detection work?
3 or more notes played together trigger chord detection: The Ultimate Piano identifies the chord and displays its name (for example "Cmaj7") above the staff, with up to two alternative names beside it. Intervals and the chord degree can be added in Settings. For exactly 2 notes, interval detection names the interval instead, for example "C Perfect 5th". Both work with any input method.
How many key signatures does the score support?
15 key signature settings are available, ranging from 7 flats to 7 sharps, each as a major or minor key. That covers all 12 major keys and all 12 minor keys, so accidentals and chord names are spelled correctly for whatever key you choose.
