"Milonga de Mis Amores" by Francisco Canaro (1937)
One great thing to notice about this milonga is the use of a musical saw. At 2:20, it is the instrument making a wavering type of sound in the background.
This is a class demo on Ochitos (Tiny Ochos) in Milonga. We looked at how to lead and follow tiny ochos, moving both linearly and circularly.
