There are so many amazing things happening online now with music and audio software. More and more is possible with software that doesn’t even live on your computer.
Noteflight, a cloud-based music notation program, is one example of this. It doesn’t compare to Sibelius and Finale (yet), but considering it’s all taking place through a website… it’s fantastic. And of course, this engenders an entire social facet of the music-creating experience that never existed until now.
A few comments, and then I urge you to go see for yourself. There are free and paid memberships. Paid will get you more instruments, greater flexibility in sharing your score with others, a much higher limit to the number of scores you can have, and other such benefits. But even in the free version you can do a great deal. I’d suggest bringing along some low expectations if you’re trying to compare this to a $500 professional notation program. But if you’re looking for sharing, collaboration, or a teaching tool with intriguing possibilities, I think you’ll be surprised and impressed.
One other feature of Noteflight: you can embed a score in a web page, as I have done below. I wrote this little snippet of chase music for my project, The Composer’s Playground earlier this year. Try scrolling around this score, clicking on notes, or playing back from the start of any measure (hover your mouse cursor above the score).
