The "Play Piano With Style" course teaches the method of piano playing known as "lead sheets" which are the favorite of professional pianists all around the world. The course consists of four lesson books and access to a website containing video explanations and demonstrations of extra tips and tricks. Live private lessons via Skype are also available at the website. Although not required, additional song books available through other online sources are highly recommended to accompany lesson books two, three and four. This piano course really works. No fundamentals of music theory are left out and the student does gain a complete understanding of all the skills necessary to eventually play any piano music they wish but the focus is on popular songs. One rule, "no stress allowed!"
