Reverse engineering songs with the aid of linoleum tetrahedron speaker

Although up to now objective on axis frequency response is not flat, the speaker is very useful for reverse engineering songs.


Why?


Because the bass notes can be very clearly heard from the linoleum vibrating sides. It is like a subwoofer but mich more clearer with excellent transient detail and damped response. For example electric bass notes with their overtones can be clearly heard while almost anything else is not heard.


When the bass note at each music measure is found by ear then the musical harmony or chords can be very easily derived by the usual 1 3 5 (7) (9) above bass rule or 6th above bass and 3rd added or 7th or 9th above bass and 3rd added [Bach].
