Robert Motherwell was a young American ‘Abstract Expressionist’ painter, printer, collage maker, and author. This study examined the music used in tango dancing classes for people with Parkinson’s disease. The main aim was to determine if there were musical features common to the most beneficial pieces. Specialised software (MATLAB) was used to analyse the music’s tempo, beat clarity, key signature and brightness or energy levels.

It had a clear, steady and always audible beat, an interesting melody and a musically cued ending. Kern, P., Wolery, M., & Aldridge, D. (2007).
