I finally understand harmonics thanks to this video - deserves 100x the views! Thank you sir! You're a great story teller and thank you for sharing your knowledge.
How do instruments use the series to create ALL the notes they play versus say stringed instruments? Is there a limitation of sorts possibly based on scale length? Thanks in advance.
great question. the physics of woodwinds differs from the brass instruments, but both have fixed lower limits based on tube length. brass uses valves to create a variety of lengths, and then the harmonics for tones. woodwinds use holes in the bore, opened or close by fingers or keys to shorten or lengthen the effective bore, thereby changing the pitch. both winds and brass have preferred key signatures and better sounding tones... awkward combinations of fingerings actually sound dicey unless the player is advanced. a simple example is the classroom recorder, a woodwind that's comfortable to play in one key, but requires strange half-holing and unintuitive combinations for many sharps and flats.
Ok.. Can you tell me you did you get a pure sine wave to have harmonics? A pure sine wave doesn't have harmonics. How did you measure the tone exactly?
Oh. Ok. I get it. You were analyzing the sound coming from your speakers. If you would input that sine wave sound straight into the spectrograph you would see that it is actually a pure tone only at its fundamental frequency
Of course. Good catch. I don’t think it’s a measurement bug , but rather an artifact of Diva, which doesn’t have a sine wave option. I used a triangle wave with a closed filter, if I remember correctly.
@@ImpliedMusic it's the same with all programs. I think it's an artifact of the speaker cone, maybe microphone membrane as well. Maybe already in the electrical circuit of the amplifier..
