Karen Peterson began learning pedal harp as a teenager, because she knew it would be more impressive than continuing with violin or piano. Then she fell in love with it, taking up the double-strung harp and becoming a Certified Music Practitioner. Since 2010, she has provided live therapeutic harp music for hospital patients, staff, and caregivers. Karen teaches harp via videoconference, focusing on adults with irregular schedules. Her books aim to help you understand and enjoy the modes.
