Reza Vohdani is a renowned name among tar (traditional Iranian instrument) players, especially within the Iranian music community that values the meticulous practice and teaching of traditional music. While Vohdani honed his skills in music theory and tar playing under the guidance of masters like Ali-Naghi Vaziri, Ali-Akbar Shahnazi, Hossein Dehlavi, and Ahmad Forutan-Rad, it is his unwavering dedication to studying, documenting, and teaching the Iranian classical music repertoire that has solidified his prominence in the field.

Can we still consider this work insignificant? Definitely not! So this is where the first use of history-based judgment comes into play.
