Someday I want to give this analogy in some talk somewhere Many people enjoy music but believe that they are tone deaf. I believe that music is at least as intuitive as speaking. Say if I tell you the following. I have the following agenda for today 1. Talk about music. 2 . Make a case that everyone has music and I stop there. I say the word music with exactly the same pitch in both the points. And then ask people do you think there is going to be a third point ? Just by keeping the note in which I say the last work people know of this is the end or there is more to come. Interestingly the end note is the same note that you started speaking in. People know that the journey is over only at the home note. This is very intuitive. Another thing which music has naturally is triads so people will always have a tendency to have 3 points. It feels unnatural to stop at 2 points. And then I will go on to show the video by mcferrel about how pentatonic scale is natural to all human beings a
