What's the point of the "in x Major/Minor" in playing songs? I vaguely remember in music class that it determines what set of notes are used to play that piece. In addition, what emotions do these evoke when used. e.g. minors are usually sad-sounding.
Is bullshit. Chromatic is where its at.
A "key" is a set of 7 musical notes that naturally work together. Starting on C, these are CDEFGAB. The space between the notes are the same in all major keys, with minor keys following the pattern ABCDEFG.
Thanks to modern tuning, keys are now chosen either at random or by what makes the piece easiest to play/sing.
Major chords are happy, minor chords are sad, but that's incredibly general and knowledge of how to evoke emotion through chord progressions is something it takes many hours of study to fully understand

Oh okay. I forgot to ask this: What about the "pairings" to make a note more vibrant perse. e.g.(I maybe wrong) A2-C3-E3 with C3 being the "main" note and C3-E3-F#3 with E3 being the main note.

Those look like inversions.
