Piano Adventures All In Two 3 Technique Performance (Softcover Book) The Piano Adventures Technique & Performance Book, with page-by-page correlations, is the essential companion to the Lesson & Theory Book and combines two essential elements of pianism. The student develops technical skills through the application of Technique Secrets, and engaging etudes and performance pieces allow these techniques to be tools for musical expression. This integration of technique and artistic performance, the sequence of Technique Secrets through the levels, and a unique emphasis on gesture to co-ordinate arm, wrist, and fingers make this series especially powerful.
