CHAPTER VII
FURTHER CONSIDERATION OF INTERVALS
As we all know, the term Major means greater. Hence, whenever there is a major interval of any name, it stands to reason that there must be a corresponding Minor or interval of the same name. As stated before, the normal second in the Major |

|
|
||||
 |
having Two Half- Steps. The Minor, |
|||
|
|
||||
|
or lesser second, then, will have but One Half-Step, hence we write C, Db, thus:— |
||||
|
--------------. We could not write C, C#, as this would not be a second, not
^.k^ including two letters. Let us treat similarly the Major Third. The Major Third from C would be E :
 |
||||
|
|
||||
 |
||||
|
|
||||
|
having Three Half-Steps.
Similarly, let us take up Sixths and Sevenths. Here they are:
Major Sixth Minor sixth Major Seventh Minor Seventh |
||||
|
|
||||
 |
||||
|
|
||||
|
The student should play, then memorize these Intervals. Make an ear test of them also.
We are now ready for a writing exercise: Write Major and Minor Seconds, Thirds, Sixths and Sevenths in the Scales of G, F, B>, indicating the number of Half-Steps in each. |
