How does the rhyme scheme of a masnawi differ from the rhyme scheme of a ghazal?

In Persian literature, the primary distinction between the masnawi and the ghazal lies in their approach to rhyme structure.1

• Ghazal: This form follows the principle of monorhyme. In a ghazal, the same rhyming sound is repeated at the end of each distich (or bayt), with the exception of the first distich, where both hemistichs share the rhyme (represented by the scheme aabaca).1
• Masnawi: This is the only major Persian poetic form that does not conform to the rule of monorhyme. Instead, a masnawi is composed of couplets in which each distich has its own independent rhyme that changes with every new pair of lines (represented by the scheme aabbcc and so on).1

This difference in rhyme scheme is significant, as the masnawi’s structure provides poets with the flexibility required for long-form epic, romantic, and didactic narratives, whereas the monorhyme of the ghazal is better suited for shorter, lyric expressions of love or mysticism.12
