Piano chords , or any chord for that matter, are formed by combining two or more scale tones (notes).You now know the tones (notes) that comprise all 12 major scales and you can play these scales smoothly (not necessarily quickly…yet!). It is now time to apply this knowledge and begin combining the scale tones to form chords. You may also see this referred to as combining two or more intervals (remember the definition from your study of major scales).
