The collaboration between Delkash and Khaledi was not only beneficial for both of them, as each one guaranteed the success of the other, but it also brought about a change in the work of construction, payment, and execution of the book. Until then, recitation was not very important, and even prominent singers considered it against honor and dignity. After Khaleghi, Delkash collaborated with Javad Lashgari, Bozurg Lashgari, Habibullah Badiei, and Ali Tajvidi, respectively. Meanwhile, his collaboration with Tajvidi was more fruitful than others, and many beautiful songs from this collaboration have been remembered. It is worth mentioning that Dalliz also composed his own songs under the nickname “Nilofar.” “Broken Instrument” is one of the songs he composed and sang himself.
