Thank you for these thoughts.
In music durations are 1 2 4
I would highly recommend checking out some traditional Macedonian folk music ... try Skopsko Oro, in 11/16 - it's wonderful music. (These types of time signatures are very common in this kind of music)
That said, I would concur that mainstream Western art music does indeed tend to be often based on symmetric measures: simple duple triple & quadruple meters (or time signatures) and compound time signatures which tend to similarly duple- triple- & quadruple-based with each dotted crotchet beat subdivided into 3
In Morse code 1, 3, 7
The overall word lengths tend to be variable. I would like to add some refinement here: yes, the lengths of the pitches are 1 and 3, I agree here - as are the spaces, which indeed are 1, 3 as well as 7;
This is exactly where the magic happens - I know you stated that you lack musical ability: please briefly bear with me, as the following is straightforward arithmetic. Counting the 'atomic' units:
>> 1 + 1 = 2 (dot + inter-letter space)
>> 3 + 1 = 4 (dash + inter-letter space)
>> 1 + 3 = 4 (dot + inter-word space)
>> 3 + 3 = 6 (dash + inter-word space)
And so on.
That means variable lengths for sums of whole words (both even and odd are possible), and the apparent rhythms that arise, to my ears, tend to be made up of pulses consisting of about 4 'atomic' units each (something like 4 semiquavers making up one crotchet pulse)
Hope that makes sense.
... playing an instrument requires perseverance, so does learning Morse ...
Agreed, that is a very good point ... perseverance tends to play a significant, arguably essential part in consistent long-term development across a range of endeavours.
Good week to you,
