The initial tune of "Triangles and Rhombuses" is notably detuned, with note pitches falling in between conventional "tuned" pitches.
The separate vignette at the end of the track is believed to be a composition named "It's Too Orangey".
Worth noting that when a triangle & a rhombus are placed adjacent they create a five-sided polygon, making it significant that this is track 5. This trend is of course followed on track six, ‘(Six)tyten’. [JayeBirdDown]
