a collection of seven different notes (plus a repeated note, creating an octave interval above the first) arranged in such a way that five of the adjacent notes are separated by whole steps while two are separated by half steps; these half step intervals are additionally spread apart from one another as evenly as possible within the collection.<\/p>\n<\/div>\n <\/div>\n <\/button>\n <\/div>\n\n \n \n
