Logiciel d'édition de partitions musicales

A scorewriter, or music notation program is software for creating, editing and printing sheet music. A scorewriter is to music notation what a word processor is to text, in that they typically provide flexible editing and automatic layout, and produce high-quality printed results. Most scorewriters, especially those from the 2000s, can record notes played on a MIDI keyboard (or other MIDI instruments), and play music back via MIDI or virtual instruments. Playback is especially useful for novice composers and music students, and when musicians are not available or affordable. Several free programs are widely used, such as MuseScore. The three main professional-level programs are Finale, Sibelius and Dorico. Multitrack sequencer software and scorewriters typically employ different methods for notation input and display. Scorewriters are based on traditional music notation, using staff lines and round note heads, which originates from European classical music. They use symbols representing durations in sound and silence, dynamics, articulations and tempo. Some also allow users to import and/or create their own symbols. Multitrack sequencer software typically uses a multitrack recorder metaphor as the main interface, with multiple tracks and track segments. Individual tracks can be edited using graphic notation in the form of a "piano roll"-guided input for the control of MIDI-based hardware and software instruments. A third approach has also emerged that combines the first two input methods into a digital audio workstation, allowing users to score parts using traditional notation, the graphic notation of the piano roll, and recording acoustic or electronic instruments in real time alongside the existing scores. With all three methods, the computer keyboard, mouse, and a MIDI musical keyboard can be used to enter music that can then be edited with traditional or piano-roll-based notation. The rapid growth of desktop computers in the 1980s saw the creation of dozens of early scorewriters (see list of scorewriters).
