-Our current western music is almost exclusively based on a 12 equal temperament diatonic scale -- basically the 7 tone (12 semitone) scale in which a semitone step corresponds to the multiplying factor of 12th root of 2 -- this we usually nowadays find on our pianos. 4/4 rhythm is most common but other ones appear, e.g. 3/4. Yeah this may sound kinda too nerdy, but it's just to set clear what we'll work with in this section. Here we will just suppose this kind of music. Also western music has some common structures such as verses, choruses, bridges etc.
+Our current western music is almost exclusively based on major and minor diatonic scales with 12 equal temperament tuning -- i.e. basically our scales differ just by their transposition and have the same structure, that of 5 whole tone steps and 2 semitone steps in the same relative places, AND a semitone step always corresponds to the multiplying factor of 12th root of 2 -- this all is basically what we nowadays find on our pianos and in our songs and other compositions. 4/4 rhythm is most common but other ones appear, e.g. 3/4.

 **Why are we using this specific scale n shit, why are the notes like this bruh?** TODO
 
+**Music is greatly about breaking the rules**, like most other [art](art.md) anyway -- you have to learn the rules and respect them most of the time, but respecting them all the time results in sterile, soulless music; a basic rule is therefore to break the rules IN APPROPRIATE PLACES, i.e. where such a rule break will result in emotional response, in something interesting, unique, ... This includes for example leaving the scale for a while, adding disharmony, adding/skipping a beat in one bar, ...

 **If you wanna learn music, firstly you should get something with piano keyboard**: musical keyboard, electronic piano, even virtual software piano, ... The reason being that the keys really help you understand what's going on, the piano keyboard quite nicely visually represent the notes (there is a reason every music software uses the piano roll). Guitar or flute on the other hand will seem much more confusing; of course you can learn these instruments, but first start with the piano keyboard.

 Other important intervals are **tone** and **semitone**. Semitone is a step from one key to the immediately next key (even from white to black and vice versa), for example from C to C#, from E to F, from G# to A etc. A tone is two semitones, e.g. from C to D, from F# to G# etc. There are 12 semitones in one octave (you have to make 12 steps from one tone to get to that tone's higher octave version), so a semitone has a multiplying factor of 2^1/12 (12th root of two). For example C2 being 65 hertz, D2 is 65 * 2^1/12 ~= 69 hertz. This makes sense as if you make 12 steps then you just multiply 12th root of two twelve times and are left simply with multiply by 2, i.e. one octave.
