Hossein Aslani, Iranian pianist residing in the US, passed away due to cancer in late January 2020. His last musical activity was an article written for Harmony Talk entitled “Iran amidst musical struggle” in 2016, his memoir entitled “I Play You Again” in the same year and his album “Symbolic Emotion” published by Arganoun Publications in 2014. Here is a brief biography of Hossein Aslani according to his own website:

UnTwelve Non-profit Organization announced the results of its 2014/2015 composition competition on January 28, 2015. Shaahin Mohajeri, an Iranian Tonbak player, microtonalist, acoustician and composer, was awarded the second prize for his piece “Castle of Babak.”

When the author was working on the piece “Playing Love” by Ennio Morricone (from the legend of 1900), he realized a failure of the Lip Technique. Needing to play a chord in the 14th position of the guitar and in order to complete the harmony, it is necessary to play a harmonic note on the 7th or 5th position; it was not possible to touch the string to play this harmonic note, because the Lip Technique is used for getting the notes and not to touch the string and producing harmonic notes. Naturally, the only possible way to touch the string was to use the nose at the required position and playing the note with the right hand, and this was the best option the author found to how to play such harmonic notes, and where the Nose Technique was generated.

Imagine that, in the course of historical research, we discover a musical piece whose compositional techniques (including form, melody, texture, and orchestration) resemble those of a second-rate 19th-century composition. But further investigation reveals that this work predates that period by 200 years. Can we still deem it insignificant? Certainly not. Here, the first major role of historical judgment becomes evident.

With this description, we have automatically included a criterion called “History”, Until we know the time of the creation of a work of art, we cannot judge whether it has been easy to create or not. Suppose that, in a historical study, we find a musical work that is similar in compositional techniques (including form, melody, context, and orchestration) to a minor work of the nineteenth century; however, our research proves that, this work dates back to 200 years prior to that date. Can we still consider this work insignificant? Definitely not! So this is where the first use of history-based judgment comes into play.

With its simple physical structure and captivating sound, the Daf never belonged to a particular culture or location, and every nation had different usages for this instrument considering their dominant customs and traditions.
