To change the tonic, we use the key signature of mos accidentals to indicate how many chroma-positive mos generators the tonic is above middle J = middle C. (A generator of a mos is called chroma-positive if the larger intervals in each generic interval class of the mos result from stacking the generator upwards. For example, the chroma-positive generator of [[5L 2s]] is the fifth, because the major third is 4 fifths up and the minor third is 3 fifths down.) | To change the tonic, we use the key signature of mos accidentals to indicate how many chroma-positive mos generators the tonic is above middle J = middle C. (A generator of a mos is called chroma-positive if the ''larger'' intervals in each generic interval class of the mos result from stacking the generator ''upwards''. For example, the chroma-positive generator of [[5L 2s]] is the fifth, because the major third is 4 fifths up and the minor third is 3 fifths down.) | ||
