I didn’t say “Islamic” scholar, I said “muslim” scholars.
I already named al-Kindi who invented a music theory and so did Farabi who did research on Persian Music. If you read the history of (oud) you’d know that it was invented by a muslim.
Here’s the rest:
Mechanical musical instrument and automatic hydraulic organ: In the 9th century, the Banū Mūsā brothers invented “the earliest known mechanical musical instrument”, in this case a hydropowered organ which played interchangeable cylinders automatically. According to Charles B. Fowler, this “cylinder with raised pins on the surface remained the basic device to produce and reproduce music mechanically until the second half of the nineteenth century.”[265]](http://www.paklinks.com/gs/#cite_note-264)
Programmable automatic flute player: In the 9th century, the Banū Mūsā brothers invented an automatic flute player which appears to have been the first programmable machine, and which they described in their Book of Ingenious Devices.[266]](http://www.paklinks.com/gs/#cite_note-Koetsier-265) The flute sounds were produced through hot steam and the user could adjust the device to various patterns so that they could get various sounds from it.[267]](http://www.paklinks.com/gs/#cite_note-266)
Timpani, naker, and naqareh: The modern timpani (kettle drum) evolved from the naker, the direct ancestor of most timpani, were derived from the Arabic naqareh and brought to 13th century Continental Europe by Saracens and Crusaders.[261]](http://www.paklinks.com/gs/#cite_note-Farmer-260)[268]](http://www.paklinks.com/gs/#cite_note-bridge-267)
Rebec and rebab: The rebec was in use since the 10th century,[269]](http://www.paklinks.com/gs/#cite_note-268) and was derived from the rebab which originated in medieval Arabic music and Islamic music.[261]](http://www.paklinks.com/gs/#cite_note-Farmer-260)
