解説Schoenberg - Variations for Orchestra op. 31 tone row mirror forms.png
English: Mirror forms, P, R, I, and RI, of a tone row (from Schoenberg's Variations for Orchestra op. 31): "Called mirror forms because...they are identical." Created by Hyacinth (talk) 06:51, 7 December 2010 using Sibelius 5.
This media depicts a tone row outside of a specific musical context. Rows consist of an ordering of the chromatic scale (no "distinctiveness"), may be used in compositions by multiple composers ("common material"), and may not be readily apparent in compositions. As such, a tone row is a musical concept or technique, which is considered too simple to be eligible for copyright protection, or which consists only of technique, with no original creative input.
