pianoplayer 3.0.0

Automatic piano fingering generator. Finds and shows in 3D the best fingering combination to play a score.

PianoPlayer

Automatic piano fingering generator for MusicXML and MIDI scores.
PianoPlayer searches for a low-effort fingering sequence for one or both hands.
You can also inspect playback in 3D with vedo.

Download and Install:

pip install pianoplayer

Optional extras:

pip install "pianoplayer[visual]"  # 3D rendering with vedo
pip install "pianoplayer[midi]"    # MIDI input support
pip install "pianoplayer[sound]"   # pygame playback
pip install "pianoplayer[all]"     # all optional extras

To visualize the output annotated score install the latest musescore, or any other renderer of MusicXML files.

CLI Usage:

Example command line: pianoplayer scores/bach_invention4.xml -n 10 -r -v -z -m
This annotates the first 10 measures for the right hand, opens 3D playback, and then opens MuseScore.

The output is saved as a MusicXML file with name output.xml.

GUI Usage

Run pianoplayer with no filename to open the GUI, then:

• press Import Score (valid formats: MusicXML/MXL, MuseScore, MIDI, PIG)
• press GENERATE (output.xml is written)
• press Musescore to visualize the annotated score
• press Quit (or q / Ctrl+W) to close the GUI

Example output, as displayed in musescore:

(If fingering numbers are not visible enough try -b option.)

How the algorithm works:

The algorithm minimizes the fingers speed needed to play a sequence of notes or chords by searching through feasible combinations of fingerings.

One possible advantage of this algorithm over similar ones is that it is completely dynamic, which means that it takes into account the physical position and speed of fingers while moving on the keyboard and the duration of each played note. It is not based on a static look-up table of likely or unlikely combinations of fingerings.

Fingering a piano score can vary a lot from individual to individual, therefore there is not such a thing as a "best" choice for fingering. This algorithm is meant to suggest a fingering combination which is "optimal" in the sense that it minimizes the effort of the hand avoiding unnecessary movements.

Parameters you can change:

• Your hand size (from 'XXS' to 'XXL') which sets the relaxed distance between thumb and pinkie.
• The beam number associated to the right hand is by default nr.0 (nr.1 for left hand). You can change it with -rbeam and -lbeam command line options.
• Depth of combinatorial search, from 5 up to 9 notes ahead of the currently playing note. By default the algorithm selects this number automatically based on the duration of the notes to be played.

Limitations

• Some specific fingering combinations, considered too unlikely in the first place, are excluded from the search (e.g. the 3rd finger crossing the 4th).
• Hands are always assumed independent from each other.
• In the 3D representation with sounds enabled, notes are played one after the other (no chords), so the tempo within the measure is not always respected.
• Small notes/ornaments are ignored.
