The Twenty Seventh Blog Of Trig - The Sound of the Initiator

I was thinking about music and sound a while back, and I thought about the way we speak of one beat being faster or slower than another. Surely, I thought, it makes logical sense to speak of frequency rather than speed. We describe this thing called a beat as going faster or speeding up, but technically it is more frequent. Speed should be confined to continuous change such as in motion.

Then I went deeper...consider a quick burst of sound. If repeated periodically we can describe the resulting rhythm in terms of its' frequency, and this is what is mistaken for speed. We talk of 'bps' or 'beats per second', which is another way of saying frequency; how frequent the beats are. Let's take a small section ('wavepacket'?) of this rhythm, and 'speed it up' (increase the frequency) until it sounds like a beat itself, we can them repeat the resulting blip and produce a new rhythm containing the original rhythm hidden in each beat. We can then repeat the process, taking a packet of these beats and increasing the frequency until they themselves are a beat, and start again.

This led me to the idea of frequencies hidden within frequencies (...within frequencies). A sound wave, or a burst of waves, can be repeated regularly to form a beat. A section or 'wavepacket' of this beat can then be 'sped up' to the point where it becomes a 'blip', the individual beats so close together that we cannot distinguish them by ear. Repeat this again and again, repeat it indefinitely to form an infinitely complex sound, with completely different characteristics dependent upon the wavelengths/frequencies you are tuned in to. Unless you were on the level of the original blip, looking 'down' on your creation, you would see (/hear) around you an infinitely massive world of vibration, most of which is out of your range. You would only hear the frequency within your range, and might believe that this was all that exists. The further down the vibrational chain you are resident, the more impossible it would seem to see/hear the top of the chain; the sound of the initiator.
