In this video, Oscar, age 13, plays Pop Goes The Weasel. This particular piece is Lesson #21 on the Musiah Piano Syllabus.
One of the challenges in this lesson is the student must pass the left hand over the right hand near the end of the piece.
Oscar is one of four boys from the Ortiz family who are learning to play piano wth Musiah, all with amazing results.
For example, Oscar learned to play this piece (Piano Lesson #21) at 3.5 weeks, and no human teacher was involved. His piano teacher is of course Musiah, the world's first Artificially Intelligent Virtual Piano Teacher.
This is a very impressive result result. Well done, Oscar. Keep up your great work.
