See if you can play this scale in the key of A, starting on the open A string and playing every note up to the second fret of the G string, which, as we already found, is also an A note. Next month we'll start talking about some other scales. Last month we discussed the chromatic scale, which includes every note available for the musician to choose from. Any other scale is a collection of notes chosen from the chromatic scale. The notes are chosen so as to create a certain tonality, or musical color.
Some scales sound happy, others sound sad.
Still others may evoke the feeling of a certain culture. Or Arabian, or Native American. Amazingly, with only 12 notes to choose from, there is the possibility of creating a huge number of musical tonalities which represent many different groups and cultures. The starting point for understanding all these scales is the major scale. I don't know.
