About Flat
Flat is a browser-based music notation editor for composing, editing, and publishing sheet music, designed around a simple interface paired with professional notation tools. It emphasizes intelligent note input and real-time collaboration so multiple people can write in the same score at once. Flat supports composing everything from solo tabs to chamber and ensemble scores, with customizable layouts, styles, and templates covering margins and spacing, staff sizing, measure numbers, and colored noteheads. It offers a large instrument library (180+ instruments, including high-quality studio sounds), advanced playback with adjustable part volumes and reverb, and the ability to upload reference audio from YouTube, SoundCloud, and MP3 files. Scores sync automatically across the web, iOS, and Android, offline editing is supported with later syncing, and the platform integrates with learning-management systems such as Google Classroom, Canvas, and Schoology. Users can also browse and explore a large community library of user-created scores. Flat is suited to composers, students, educators, and hobbyists who want to collaborate and work across devices. It is available via web browser and as iOS and Android apps. Pricing is freemium: a free tier covers basic use, while paid "Power" plans (subscription, with a one-time lifetime option) unlock unlimited scores, premium instruments, and advanced features.
About MuseScore Studio
MuseScore Studio is free, open-source desktop software for writing, editing, playing back, and exporting music notation. It is a full-featured scorewriter maintained by an active open-source community and is distinct from the MuseScore.com sheet-music sharing and subscription website. The application provides professional notation tools for creating scores for a wide range of instruments and ensembles, with built-in playback so compositions can be heard as they are written. It supports note entry via computer keyboard, mouse, and MIDI keyboard, and exchanges files with other programs through MusicXML, MIDI, and additional formats. Scores can be exported to formats such as PDF and audio, and the software is extensible through plugins. It is available in many languages and runs as a downloadable desktop program. MuseScore Studio is aimed at composers, arrangers, students, teachers, schools, choirs, and orchestras, from beginners to advanced users. It runs on Windows, macOS, and Linux, and can be installed directly or through the MuseHub application. Its pricing model is entirely free: the program is open source with no cost and no usage limitations on the software itself.
