On musical modes, harmonic intervals, and transitional elements in movement
At the beginning stage of Ido’s locomotion system, we are always returning back to a pre-determined transitional point, creating a clear sense of home - a “key” or “mode” that characterizes what can be executed, much like the tonal center of a musical scale / song.
In music, the pitches of notes can be differentiated one from the next, in what is called a horizontal interval. But there is also difference between the pitch of a note and this essential tonal center.
That is to say, it’s not just a question of the relationship of an element to the next one in a sequence, but also the relationship between an element to this transitional point.
By constantly leaving and coming back to this transitional point, carving countless trajectories to and from, we acquire the kinesthetic equivalent of an internalized sense for that tonal center - it becomes a place you can easily leave and come back to, like any musician who becomes proficient with a musical scale.
