Providing the same driving distances and same level of playing and course structure and spectator amenities. May include doglegs, bunkers, water hazards, tree hazards, rough, clubhouse, gallery, and concessions as in present golf courses. Professional and practice courses built on small land areas.

Abstract: Shapes formed by various series of interconnected straight lines representing lines between finger positions forming chords on musical keyboards form a system and method for learning finger positioning to form chords and finger movements to change chords on a musical keyboard. All thirty-six triads can be formed by eight triad shapes for forming finger positions to create the triad chords by moving the finger positions to different locations along a keyboard. All four finger chords can be formed from sixteen four finger chord shapes. Chord trees are families of chords formed by moving one or more fingers from each triad chord or four finger chord to raise or lower notes, merge two notes into one, or split one note into two notes thereby forming all new chords and harmonies.

Abstract: A relative chord method for playing a series of chords on a music keyboard by prescribed finger transitions from one chord to the next dependent upon the musical interval between the chords.
