I just want to say how grateful I am for the entire team at Flat! You guys are so amazing. With Flat, I have taken music from being a hobby to actually earning commissions and writing for professional ensembles and recordings. Wow!

Since I've joined Flat, I've been able to grow as a musician and learn things I may have not ever learned in the music world. Again, I wanted to thank you for the amazing journey you have given me, through the monthly challenges, Flat Blog Posts, and a wonderful community that I take a responsibility to protect along with other great users

Please keep up with your platform—it is a wonderful tool and has propelled our son into writing his own music in a way that no other platform or app has been able to.

Let me thank you for producing this tool! I have found it to work intuitively well, being able to enter some arrangements on my first attempts with the app on iPhone.
