Sonic Pi: having fun with note rings in minor pentatonic, used as licks. The little graphs created by the spark function help understand those licks.

	def play_lick(lick,root, scale, time)
	spark lick
	lick.each{\|note\| play((degree note, root, scale)) ; sleep time }
	end

Sonic Pi script to play with licks (short melodies notated in scale degrees). The function to convert degrees to notes is cobbled together from the built-in `resolve_degree` and `resolve_degree_index` methods.

	# Sonic Pi script to play with licks (short melodies notated in scale degrees). The function to convert degrees to notes is cobbled together from the built-in `resolve_degree` and `resolve_degree_index` methods.
	# Defining two new functions. Once defined, they don’t need to be included in other scripts.

	# Lick player
	def play_lick(lick, root, scale, time) # A “lick” is a list of scale degree numbers, with a set timing (i.e. “isorhythmic”).
	spark lick # Show the lick as a text-based graph
	lick.each{\|note\| play((degree_to_note note, root, scale)) ; sleep time } # Convert each degree number into a note and play it for the set amount of time. This function doesn’t use all the other `play` arguments such as `release:`and `amp:`. Could be useful in a future version, especially for timing.
	end

	DEGREES = {:i => 0, # Thought these were defined by default. They’re necessary for the degree conversion.

“Rranding Ring Chains”, coded by Alex Enkerli, March 24, 2016. Playing with ring chains in Sonic Pi, using a previously-built script to play with “licks”. <https://gist.github.com/Enkerli/0687533338c5e40516fc> In several cases, the basic “lick” using degrees 3, 5, 1, and 4 of a given scale makes for intriguing combinations, once shuffled and cut…
