I know there is a relationship between music and mathematics so for someone with an engineering background all should be OK.
On to the keyboard, 88 keys – all in groups of eight, and notes that are an octave apart played together sound good. Marvelous !
On to musical notation, hang on there are nine positions here, not the eight on the octave. And they are not from A to G - as would be logical- but from E to F. And two notes an octave apart are in different parts of the stave – the lower F is between the lines, the upper on the line.
So thinks – I suppose this is because “middle c” is in the middle of the stave- but hang on a minute it is not, it’s in the space above the middle.
Aaaarrrrgggghhhh …………………
