The dimensions comes initially from the phrase scala, Italian for staircase and it’s a collection of ascending or descending notes. In a significant scale that is within the mounted sample Tone Tone Semitone Tone Tone Tone Semitone. In the event you observe this sample you can begin on any notice and work out the main scale that pertains to it.
So in case you take a look at C the main scale will in fact begin on C. Then the subsequent notice will probably be Tone greater which is D (as a result of C# is a half a tone greater than C and D a half tone greater than C#). So the primary two notes of your scale are C D.
The third notice is a Tone greater than the second notice D which is E (as a result of D# is a Semitone greater than D and E is a Semitone greater than D#). So the primary three notes of your scale are C D E.
The fourth notice of your scale is simply a Semitone greater than the third notice E, however as a result of there’s solely a Semitone hole between E and F the fourth notice continues to be pure i.e. F. (In the event you noticed E# written in a bit of music that’s the identical as F). So the primary 4 notes of your scale are C D E F.
The fifth notice is a tone greater than F and since there’s an F# a Semitone greater than F after which G is a Semitone greater than that then this fifth notice is G. So the primary 5 notes are C D E F G.
The sixth notice is a tone greater than G and since there’s a G# a Semitone greater than G then it’s the pure notice a Semitone greater than G#. Nonetheless, this isn’t H as all notes go from A to G after which begin on A once more so this notice is A. So the primary six notes of C scale are C D E F G A.
The seventh notice is a tone greater than A and as there’s an A# a Semitone greater than A after which B is a semitone greater than A# then that is B. so the primary seven notes are C D E F G A B.
The ultimate notice is simply a semitone greater however as there isn’t a B# between B and C (B# would equal C) this notice is C. So that you at the moment are again the place you began with notice 8 which is at all times the case and your C scale is C D E F G A B C.
