Ortiz always does an excellent job of conveying the importance of a relaxed technique when you play the repetitive rhythms and bass lines of South American music on harp. Paraguayan harps have such a full sound, in part due to less tension on the strings; his technique allows the instrument's rich tones to fully resonate. He challenged us to look at our own technique but was careful to add that he's not advocating we change it. I love that he is all about efficiency of movement with the least amount of tension, and to be conscious at all times of what we are doing and how we are doing it.
