Frances Clark

Frances Oman Clark (March 28, 1905 – April 17, 1998) was an American pianist, pedagogue, and academic who authored, co-authored and edited many widely used piano method books, most notably The Music Tree series. Her 1955 publication, ''Time to Begin'', introduced the concept of teaching music reading by pattern recognition, thus pioneering the "intervallic method," which "revolutionised" the teaching of music reading.
