This paper presents a novel approach to visualiz-
ing the time structure of musical waveforms. The
acoustic similarity between any two instants of an
audio recording is displayed in a static 2D repre-
sentation, which makes structural and rhythmic
characteristics visible. Unlike practically all prior
work, this method characterizes self-similarity
rather than specific audio attributes such as pitch
or spectral features. Examples are presented for
classical and popular music.
