Cicada Chorus

Cicadas do not stridulate like crickets. They buckle a ribbed membrane called a tymbal thousands of times a second, and a largely hollow abdomen amplifies the result. It is the most efficient sound-production system in the insect world.

Massed choruses rise and fall in slow waves as groups synchronise and drift apart - an aggregate rhythm no individual is producing.

Male cicadas calling from tree trunks and branches to attract mates, strongly temperature-dependent.

Commonly heard: Warm temperate and tropical woodland worldwide; in the eastern US, periodical broods emerge on 13- and 17-year cycles.

Through the seasons: Mid to late summer for annual species; periodical broods appear for a few intense weeks.

Dense, harmonically rich, amplitude-modulated noise with pronounced slow swells.

Frequency profile: Broad energy centred in the upper mids with harmonics extending high; some species are startlingly loud.

• Heat
• Intensity
• Strangeness
• Summer at its peak

Creative work

Nothing communicates oppressive heat faster; excellent for scene-setting.

Relaxation

Generally too intense.

Meditation

Occasionally used as an intentionally overwhelming object of attention.

Focus

Distracting for most people.

Sleep

Not recommended - the swells are too dynamic.

Paste any of these into the Studio, or adapt them. They are written to work with ElevenLabs Music and most other text-to-music tools.

• Blazing summer afternoon, dense cicada chorus, heat haze, sparse guitar harmonics, drone ambient
• Tense cinematic ambient with cicadas, dry wind, distant thunder building

• Some cicadas exceed 100 dB at close range, among the loudest sounds produced by any insect.
• Periodical cicadas' prime-numbered life cycles are thought to make it hard for predators to synchronise with them.
