Students take the division of the string using the intercept theorem by the Let’s Hear Thales’ theorem” scenario and start investigating synergies of consonances and dissonances derived by the triangles produced in each section. Students experiment with their own similar triangles by composing their sequences of tones derived from their sides and eventually by constructing the virtual instruments to play them. This scenario introduces an extension using areas also instead of strings. For this reason teacher introduces “round” and not exact numbers.
This Scenario can also be combined with “House of Chords” from which a selection of lesson plans can be adopted at the teacher's descretion.
