At Ocean Adi Basant is subsumed under Vasantha Carnatic along with Shuddha Sohini and Vasant Pancham , as having only shudh ma .
Further investigation could show which prakars have both ma , which ones do not have kom re but rather shudh Re ( sound like Hemant at times ) , which ones are identical to Shuddh Basant etc ....
