Rangarajan Posted March 7, 2016 Share Posted March 7, 2016 Hi, When I was examining the various modes/scales in the pre-defined 'modes library, I noticed that the following modes all have the same interval as 'major scale: (raga-shankarabharanam mela-shankarabharanam xin ararai rast peruvian-major dastgah-mahur dastgah-rast-panjgah hypolydian-medieval lydian-greek ionian major) In other words, the expression: (pitch-to-interval (expand-tonality '(c4 <a-mode>))) returns the same interval list for all the above modes. I can understand that 'ionian' is the same as 'major', but finding the others to be the same as major scale was a bit surprising. Looks like other musical cultures such as India, Iran, Peru, and Ethiopia used the same major scale under a different name. Can anyone throw further light on this coincidence?

opmo Posted March 7, 2016 Share Posted March 7, 2016 Indeed, there are many tonality names with the same intervals. Quote Link to comment Share on other sites More sharing options...
