I came across a high-speed recording of bowing on a violin string today, and thought it would be interesting to try to analyze it with the new version of the Musical Gestures Toolbox for Python. This is inspired by results from the creation of motiongrams of a high-speed guitar recording that I did some years ago.
Here is the original video:
From this I generated the following motion video:
And from this we get the following motiongram showing the vertical motion of the string (time running from left to right):
This motiongram shows the horizontal motion of the string (time running downwards):
Great example of a sound-producing action!
