My Take
I doubt that my students learned anything. It has been a horrible resource. One time I assigned my students homework on smart music and the next week they came in and they were all playing wrong notes. I gave it a second chance but the same outcome.
How I Use It
I use it to assign my students homework every week. They always complain about it and I am an understanding teacher, so I looked into it further. All of the notes are wrong and it is teaching my students false notes and rhythms. I would never recommend this to any teacher who wants their students to succeed.
