Scales are tone groups or sets. They are typically used for training and learning what tones work together for any given situation. The tones in scales can be derived in a number of ways; the most common starting points are the Major & Pentatonic scales.
The term scale generally relates to playing a series of single pitches in alphabetical order, ascending and descending. Yet, they can be played in different alpha orders and can still be called scales. When using a scale for melody, we tend not to think of them of scales, but as melodic materials.
Our main goals with scales
We often learn 'patterns' at the beginning to get functional in all keys. Yet, 'patterns' are meant to be transcended. And, there are many many approaches to all of this. Our quest is to form our own.
