Well, we have had a dry technical description of what a scale is ??” but the particular thing is that where is the music in it? Okay, in melodic terms, a scale can be described as a palette of notes that you can choose from to put together chords, accompaniments, harmonies, melodies solos and just about everything. Look at it this way ??” you are in need to acquire any language depending upon your choice e.g. English before you can be a poet. Scales are the language of music, and there are a lot of different modes to put them together to keep things interesting. If you have no understanding of scales you would be a little like trying to write a verse without using real words – it could work and be very cool in some cases, but the probabilities would be much better if you stick to a usually understood medium, which is what scales/language are.
