In the previous section you learned how to build major scales. Can we use the same technique to build minor scales? Absolutely. We can use the fifth note of the A minor scale to build the E minor scale.
Note that we raised the second note to ensure there is a half step between the second and third notes of the E minor scale.
Can we also count down a fifth to build a related key? Again, the answer is yes. We will use the A minor key to create the D minor key. We still maintain our rule of half steps between notes two and three and between notes five and six. In the E minor key the six note is lowered a half step to maintain our rule.
You may have realized by now that there is a relationship between the major and minor scales. Generally, the sixth note of the major scale can be used as the keynote of the natural minor scale. The relative minor scale you create will have the same key signature of the major scale. When you are seriously composing music, or just having fun, you should try modulating from the major key to its relative minor key and vice versa. The minor key has the same tones, although it starts on a different keynote. The changes between major keys and their relative minor keys produce an interesting musical effect. Most importantly, keep on experimenting. Your successes will make the effort worthwhile.
