Music notation software is a type of computer program that allows musicians and composers to create, edit, and print sheet music. These tools provide a digital platform for writing musical scores, making it easier to visualize and share compositions. Users can input notes, rhythms, and dynamics using a mouse, keyboard, or MIDI instrument. Many music notation software options also include playback features, enabling users to hear their compositions in real-time. Popular programs like Finale and Sibelius offer a range of functionalities, from simple note entry to advanced orchestration tools, catering to both beginners and professional musicians.
