Another scale lesson today! Actually, there's a few cool things going on here. More than just playing through a scale. The diagram breaks it down so let's look into what's going on.
What you see is four sets of three bars that are virtually identical. Yes, it's twelve bars but consider them as four sets of three bars. Here's why. The first bar of each set is an ascending A7 arpeggio. The last two bars are the complete A Major scale descending note by note from the high octave note. That's a great way to practice scales - ascend through an arpeggio and return with the full scale. Of course, you can mix it up start with the scale, return with the arpeggio. Play both ascending, play both descending. Whatever, get creative! This is excellent for developing hand skills, musical knowledge, improvisation capability, and hitting target notes.
Notice that we've also added one extra feature to this music lesson. The very first note of each set is the root note. On each set of scale progressions the root note drops one scale step of the A Major scale (A - G# - F# - E). The entire piece preserves the tonality of the A Major scale (we encourage you to practice the whole diagram as a complete piece once you understand what each of the four sets of bars is doing). Getting inspired by this may add both colour and groove to your playing depending on what style of music you play.
