Quoting Nooshin, The distinction between gusheh and mode is rarely discussed in the literature, but is often implied in the terminology used.
Of those who do discuss this (briefly), Hormoz Farhat suggests that the Persian maqām ('position') is equivalent to 'mode', and certainly prior to the development of the dastgāh system, this would have been the main local term signifying mode or melody-type (as still used in related traditions in the region.
[1]According to Farhat, Before the development of the system of the twelve dastgāhs, traditional music was known under the genus of various maqāms.
In Turkey and in the Arabic-speaking countries , the maqāmāt (Arabic plural for maqām) is still the basis of classical music.
The Sanskrit theorist Pundarika Vitthala noted the names of the Persian maqams in his sixteenth-century treatise Ragamanjari.
