Alejandra Mesliuk: Fewer notes, but melos, more sentence. Example of a cadence l-lV, using only maj7 arpeggios, raised me on several occasions the question of how to use the arpeggios of musical form. I hope the example will be helpful. Learn how to break the systematic way of playing arpeggios is one of the keys. ;-)
