 Salzedo collaborated with Lucile Lawrence to write "Method for Harp" (1927), where he furthered his notations using specific techniques like these.Archambo calls post-1919 compositions part of Salzedo's "mature period" and writes that, aside from his pedagogical pieces, melodies are not supported by traditional harmonies, but are accompanied by sound clusters.Archambo states that Salzedo's main goal in composing was to "make available to the harpist and contemporary compose every possible sound and effect on the instrument."
