World Listening Day 2022: Listening Across Boundaries

Today we announced that the theme for World Listening Day 2022 will be “Listening Across Boundaries.” I’m super excited to have been chosen as the theme creator for this year and that my choice of theme seems to resonate with so many and in such interesting directions.

World Listening Day is celebrated every year on July 18th.

Ocean World of Sound – 30 Day Challenge

Check out our new YouTube Channel “World of Sound” and in particular, our 30 day challenge. For about 2 minutes per day, build your active listening skills and explore a variety of underwater soundscapes. It’s a great way to connect with the ocean, pause and collect yourself, and gain listening tools. Let us know what you think!

World Listening Day Workshop 2021

Join us on world listening day July 18 2021 for an ocean soundscape experience. We will begin with a “tune in” exercise to tune our ears, and then explore underwater sounds, including never before heard recordings from the MesoAmerican Reef System. We will have open discussion on discoveries and methods and look forward to your input and insights.


The Unquiet Earth World Listening Day 2021



Who: You! Anyone interested in the ocean, sounds, and learning to ‘tune in’ more effectively. All experience levels welcome.

What: World Of Sound Workshop. Come explore the ocean soundscape with us.

When:  Sunday July 18, 4-5pm Eastern

Where: Online! We will be using Google Meet: https://meet.google.com/kmi-raih-kjd

Why: The ocean has unheard songs and untold stories. Let’s explore together.

How: With appreciated support from the National Academies Keck Futures Initiative!

(This workshop is in memory of beloved colleague Mark Ballora, sonification expert and friend, who left us too early on this day two years ago.)

Tune in May 28 5pm Pacific / 8pm Eastern for a virtual concert/talk on my soundscape compositions including live Q and A

Craft In America – Summer Virtual Concert Series: Heather Spence

Heather Spence is a marine biologist and musician who explores ocean soundscapes by recording, analyzing, and composing music from underwater sounds. She will be premiering new music compositions that explore the nightlife of coral reefs and incorporate underwater recordings and sonified data collected for her scientific research. Can listening to nocturnal mystery fish and crackling shrimp reveal any insights for ocean conservation? She will also be speaking and answering questions about her work.

Laz Tiyas and Flory Jagoda

This Friday we lost our Nona Flory – composer, musician, singer, mentor, performer, reviver of the Ladino language… We are grateful for the time we had together and honored to help carry on her amazing musical legacy. Flory Jagoda taught Laz Tiyas her songs by ear, to carry on the tradition of songs passing down from women to women.

LAZ TIYAS. A group of women came to Flory in 2008 and asked her to teach them her songs. Since then they have been singing together every week. The name “Laz Tiyas” honors her aunts in her song of the same name.

Laz Tiyas include:

Tiya Mazalta – Janet Dunkelberger – Arlington VA
Tiya Grasya – Maya Giacobbe – Arlington VA
Tiya Luna – Heather Spence – Arlington VA
Tiya Paloma – Martha Halperin – Arlington VA
Tiya Estreya – Cory Giacobbe – Pristina, Kosovo

RSVP for this event

November 12 12:00 pm – 2:00 pm Pacific
Location: Zoom

Heather Spence (Marine Biologists and Composer) on “Underwater Sound Research:

Music of Marine Biology”

Cheryl Leonard (Composer and Instrument Builder) on “Phantom Limbs: Composing Music Amidst the Sixth Extinction”

The LASERs are an international program of evening gatherings that bring together artists, scientists, thinkers, inventors, and scholars who are working on paradigm shifts for informal presentations and conversation with the audience. Chaired by Piero Scaruffi. Visit www.lasertalks.com for more details.

Heather Spence is a marine biologist and sound artist who combines science and art to harmonize human-environment interactions. She has taught courses on animal behavior, behavioral neuroendocrinology, sensation and perception, personality, etc. Her Passive Acoustic Monitoring research program on the MesoAmerican Reef is featured in National Geographic’s television program “When Sharks Attack”, and is explored in her composition for viola da gamba trio, Vale la Pena?. She composes music inspired by, and inspiring, conservation and performs internationally as a cellist and gambist. She currently advises on science and acoustics at the US Department of Energy and is co-leader of the transdisciplinary Ocean Memory Project/

Cheryl E. Leonard is a composer, performer, and instrument builder whose works investigate sounds, structures, and objects from the natural world. Her projects cultivate stones, wood, water, ice, sand, shells, feathers, and bones as musical instruments, and feature one-of-a-kind sculptural instruments and field recordings from remote locales. She uses microphones to explore aural worlds within her sound sources, and develops compositions that highlight the unique voices she discovers. Her recent projects focus on climate change and extinction of species.

Marine Biologist response to book The Girl Who Danced With Dolphins

Thanks for joining my Facebook Live event with Cory Giacobbe! If you have any further questions about the book, ocean science, dolphins, or anything else, let me know!



Here’s a photo of me recording dolphin sounds at an aquarium in Mexico.

Mark Ballora

Mark Ballora, a dear friend and collaborator, was a pioneer in acoustics and “sonification” of data. A memorial service is being held this weekend at Penn State, where he was a professor of music technology.

Naturally I collected my thoughts about carrying forward his energy and vision in musical form. This short composition (<2.5 min) incorporates a musical cipher of his name, coral reef sounds, and audio recordings he made of me pitched at his vocal frequency, as a symbol of my dedication to seeing his voice, missions, and work are carried forward.

Mark and I met at a National Academies Keck Futures Initiative conference and are in the middle of a NAKFI grant on sonifying ocean data: “Layers of Meaning: How the Ocean’s Natural Acoustics and the Music of its Datasets Can Reveal Hidden Connections”
