“For me, throwing stones in the first intifada was a way of expression,” said Ramzi Aburedwan, who was famously photographed as a boy throwing a rock in 1988, and now runs music schools in Palestinian refugee camps. “The tool was the stone in the first intifada, and today it’s music.”

“Sound and words reflect the situation,” Mr. Aburedwan added. “I can’t do a song talking about nature and beauty and peaceful things when I’m seeing every day more than 10 videos where some youths are executed.”

But Basel Zayed, a composer, performer and music therapist from East Jerusalem, criticized the instrumentation of the new songs for “using the same fraction of a rhythm and just looping it” and their lyrics as “not very expressive, the main two words are like kill or do or bomb or explode.”

“It was done as a reaction, and that’s a shame because it gives a very negative picture as to how Palestinians can express themselves,” Mr. Zayed added. “I don’t think coming up with a song so fast serves our message in the best way. It’s good to let things sink in first. When you’re inside the trauma, you don’t really understand what’s happening to you.”

New tunes pop up online every day, many by little-known artists and with low production values — the YouTube video for “Intifada of Knives” is a crude collage showing the Dome of the Rock with fire underneath and a man with a kaffiyeh covering his face holding a slingshot, then a dagger that eventually is stained with blood. Several simply lay spoken-word rants over Arabic percussion.
