I am an advocate of teaching phonics to children, and I think a variety of methods to teach phonics is useful. Music is one way, and this Phonics Song is a great video to teach skills to kids in a fun way. This makes it an effective learning tool. It utilizes the visual and auditory modes of learning to appeal to both the visual learners and the auditory learners.
This is a great video for a classroom or home schooling. It teaches the alphabet and phonetic sounds along with sign language for the alphabet.
I had a couple of students in my classroom one year who needed and were learning sign language. My whole class, including myself, learned along with them. It’s a great skill for all students to have.
