“How do time signatures work?” “What does 'the key of A' mean?” “How can I learn to improvise?”  “How can I set the lyric I wrote to music?” This course offers comprehensive instruction in the language and mathematics of music. It is a good option for someone who knows an instrument but cannot read music, or someone who reads, but needs to strengthen knowledge of theory. The theory course is also helpful to musicians who want a deeper understanding of composition or who want to put their musical ideas in print.
