# SCALE CONSTANTS
#
# Scales are defined by the following:
# 1. a constant for the name which is used as an array index,
# 2. 3 arrays. The first is used for scale size. The second and
# third provide different ways of looking up a note.
# Half-tone (chromatic) offsets are used in each case.
#
# Each scale is defined twice; i.e., there
# are two forms of offset lookup tables.
# The first table has the form of offsets in half-steps
# from the base scale note; e.g.,
# a major scale consists of 0,2,4,5 for the unison, major
# second and major third.
# The second table has the form of offsets from the last
# scale note; e.g., a major scale consists of 0,2,2.., etc.
#
# These two arrays are referred to as
# "baseScale" and "lastScale". With the first form
# the note is calculated from the base note of the scale,
# e.g.,
# note = C + baseScale[IONIAN][FIFTH]
#
# The lastScale array permits easy access of the next
# scale degree from the previous, e.g.,
# nextnote = lastnote + baseScale[IONIAN][curindex]
#
# Functions:
# riff printScale(scale) - print the string name of the scale
#
# church modes
