Our mission

Every brain deserves
to reach its potential.

Training the ear can change the brain.

Discover our approach

Why music, why early?

A finer challenge for a growing brain.

Music can demand finer pitch perception than everyday speech. Patel’s OPERA hypothesis proposes that this precision, paired with enjoyment, repetition and attention, can strengthen the auditory networks they share.

In one study, nine-month-olds joined twelve 15-minute sessions over four weeks. Caregiver-assisted musical play led to stronger brain responses to changes in music and speech timing than socially matched play.

BBB’s central hypothesis is that early musical challenges can shape the auditory system’s structure and function in lasting ways. We want to test how growing listening precision and biological adaptation develop together.

Read the research

This measured neural timing responses after a bundled music activity. It did not measure tissue growth or establish results from Bell or our app.

The development window

These early years happen once.

We want to make the most of early sensitive periods, while neural circuits are forming, adapting and being refined. Begin with shared songs and movement, then explore finer listening challenges as your child grows. Learning continues beyond these early years.

Why early experience matters →

  1. Before birth

    Begin with something familiar.

    A gentle pulse

    Return to a gently rhythmic song. Let its pulse guide your own movement.

    A familiar melody

    Sing a comfortable melody you enjoy returning to.

    Return to the same song

    Make the same song part of your day. There is no response to test.

    Research behind this stage

    Exposure in the last trimester; recordings after birth and at four months.

    Melodies heard before birth can leave a measurable memory trace after birth.

    Partanen et al., 2013 (opens in a new tab)

    Returning to a familiar song adapts the study’s repeated-listening idea. Gentle movement is a separate play suggestion.

    What researchers measured

    Postnatal EEG after repeated prenatal melody exposure.

    What this does not establish

    The study found lasting sound responses, not a map of fetal brain activity or evidence of general cognitive enhancement.

    Reading the brain illustration

    Gold marks general hearing anatomy, not regions localized by the prenatal melody study. This same reference shape is used at every stage; it is not a fetal brain or an individual scan.

    UTHealth · auditory anatomy (opens in a new tab) ↗

  2. Birth–6 months

    Let them hear it. Help them feel it.

    Feel the pulse together

    Hold your baby and gently sway with the pulse.

    Leave room for a reply

    Sing a short phrase, pause, then respond to your baby’s sounds.

    Something familiar

    Return to a familiar song. Enjoy their response without scoring it.

    Research behind this stage

    Infants aged two to three months.

    In two- to three-month-olds, speech activated left temporal regions, including the superior temporal gyrus.

    Dehaene-Lambertz et al., 2002 (opens in a new tab)

    Short phrases and pauses make room for listening and vocal exchange. Familiar songs and swaying are separate play suggestions.

    What researchers measured

    fMRI while infants listened to forward and reversed speech.

    What this does not establish

    This was a speech-listening study, not a training trial. It does not establish that these activities accelerate brain development or that every infant follows the same schedule.

    Reading the brain illustration

    Gold marks one region reported in the speech-listening study. Other regions also responded. The illustration does not show measured activity, developmental maturity, or your child’s brain.

  3. 6–12 months

    Make room for a little back-and-forth.

    Share a rhythm

    Sway to a repeating rhythm. Pause when your baby turns away.

    Take a sound turn

    Copy a sound your baby makes, then leave space for another turn.

    Repeat a short phrase

    Repeat the same little melody during play, with no right answer required.

    Research behind this stage

    Nine-month-old entrants; twelve 15-minute sessions over four weeks.

    After a structured music program starting at nine months, infants showed stronger brain responses to changes in music and speech timing.

    Zhao & Kuhl, 2016 (opens in a new tab)

    Shared rhythmic movement adapts one part of the music program. Vocal turns and familiar phrases are additional play suggestions.

    What researchers measured

    Music versus social-play groups, followed by MEG recordings.

    What this does not establish

    The intervention combined music, movement and social participation. It did not test these brief activities or Bell, or establish brain growth, intelligence or lasting language gains.

    Reading the brain illustration

    Gold represents the broad temporal and prefrontal groups analyzed in this study. The researchers used an infant template and averaged across gyri and sulci. These atlas parcels are illustrative approximations, not exact activation boundaries.

  4. 1–3 years

    Turn their curiosity into a turn.

    Find a pulse together

    Copy your child’s bounce or clap. Try a few gentle claps together.

    Copy a sound

    Offer a comfortable high or low sound. Leave room for a vocal reply.

    Hear it again

    Repeat a short pattern. When they understand the choice, ask whether another version matches.

    Research behind this stage

    Children aged 2½, 3½ and 4½; the youngest group overlaps this stage.

    Children as young as 2½ matched a beat more accurately with a person than with a machine or recording.

    Kirschner & Tomasello, 2009 (opens in a new tab)

    Clapping together adapts the social timing idea without instruments. Vocal and memory games are separate play suggestions.

    What researchers measured

    Behavioral comparison of drumming with a person, machine or recording.

    What this does not establish

    The study did not test one-year-olds, clapping, pitch practice or a training benefit. Follow your child’s participation rather than expecting synchronization by a birthday.

    Reading the brain illustration

    Gold marks auditory and motor/premotor regions relevant to listening and coordinating movement. The separate imaging study examined adults; the child drumming study measured behavior, not regional activity. Whole atlas parcels provide broad context for smaller functional areas, not an exact activation map or evidence of growth in a child.

    Listening & movement anatomy · Chen, Penhune & Zatorre, 2008 (opens in a new tab) ↗

  5. 3–7 years

    Small challenges. Growing skills.

    Keep a pulse. Copy a rhythm.

    Clap steady beats together, then echo a short rhythm.

    Notice a change. Echo a sound.

    Compare clearly different notes or echo a comfortable sung phrase.

    Remember through a pause

    Hear a short pattern, pause, then recognize it. Try a delayed echo once an immediate echo feels easy.

    Research behind this stage

    Children aged four to six; twenty training days over four weeks.

    In one study of four- to six-year-olds, four weeks of structured music activities changed brain responses to musical sounds.

    Moreno et al., 2015 (opens in a new tab)

    Listening, rhythm and voice reflect themes in the group program. Delayed recall and silent anticipation are product adaptations, not outcomes established by this study.

    What researchers measured

    Music versus French-language group training, with auditory EEG recordings.

    What this does not establish

    This was an intensive group program, not these brief activities or Bell. EEG changes do not establish regional growth, an individual readiness level or general intelligence gains.

    Reading the brain illustration

    Gold marks auditory regions involved in pitch and melody processing, supported by a separate adult fMRI study. Heschl’s gyrus is represented by transverse temporal parcels, with superior temporal cortex as broader melodic-processing context. The child training study measured scalp EEG, not these anatomical boundaries or tissue growth. This reference is not a map of an individual child’s activity.

Beyond childhood

Music to grow with.

From a familiar song to a note they recognize by name. Build listening skills to keep practicing and enjoying throughout life.

Recognizing a note. Knowing it by name.

Absolute pitch means identifying a note without a reference tone. Our separate identification pathway works toward that ability through gradual listening practice.

Chord practice is available now. A separate single-note assessment is planned.

Explore the listening skills
Skills, assessment and lifelong learning

Illustrative learning goals · Each child’s progress is individual.

  • Beat match · Rhythm and meter

    Practice joining a beat and recognizing how a rhythm changes.

  • Pitch discrimination · Vocal pitch matching

    Explore pitch comparisons and matching a comfortable sung sound.

  • Auditory memory · Audiation

    Recognize sounds after a pause and explore a familiar phrase through silence.

The app includes six skill paths, including memory recognition. Timing checks currently use taps; clap scoring and delayed clap or vocal recall are planned.

General skill levels use two independent checks, including a later confirmation. These are app progression criteria, not measures of brain development.

Available now: Learned chord recognition

Practice a growing set of fixed chords, with the child answering aloud and a caregiver recording the first response. Completing the chord program begins maintenance.

Planned assessment: Independent single-note identification

A separate assessment is needed to show that a child can name individual notes without a reference. Completing the chord program does not award this result.

Explore chord identification →

One small child-training study reported eventual success on a separate single-note test. It did not test this app or establish a completion age or lifelong guarantee. Sakakibara, 2014 (opens in a new tab)

Absolute-pitch ability has been observed in older adults, although note-naming accuracy can change with age. Research does not establish that childhood training guarantees unchanged ability at 76.

This research did not follow children trained with our app into older adulthood. Athos et al., 2007 (opens in a new tab)

Bell · In development

Meet Bell.
Our mission, made for home.

A ceiling projector and sound system in development for pregnancy through your baby’s first year. You lead the rhythm; your baby watches, listens and moves with you.

Bell is designed to make shared listening, attention and repetition easy to bring into family life. Familiar sounds, gentle movement and your participation turn our research-informed approach into moments together.

Pregnancy to twelve months

The first year

For shared awake time. Follow your baby’s interest and pause when they turn away.

3–6 months · Pair sight with sound

Tap along to a rhythm your baby can see and hear.

Practice & research

Watch the ceiling cue approach, then meet the sound with a gentle tap of your own. Your baby sees and hears the same pulse together. Repeat a steady pattern, then explore a small tempo change.

Three-month-olds detected tempo changes after synchronized audiovisual exposure. At five months, synchronized sights and sounds also supported rhythm discrimination in laboratory tasks.

Bahrick et al. · 2002Bahrick & Lickliter · 2000

Beat Sync practice in year one is for the caregiver. A 2026 study found more organized music-related movement by twelve months, but no beat-matched movement in the tested age groups.

Nguyen et al. · 2026

6–12 months · Add felt rhythm

Hold and support your baby as you follow the light from side to side.

Practice & research

Hold and support your baby while a slow wall cue guides your gentle sway. Follow the strong beat at a comfortable pace. Explore groups of two, then three, across separate moments.

Seven-month-olds bounced on every second or third beat later preferred the matching rhythm grouping. Their own movement mattered; watching someone move did not produce the effect.

Phillips-Silver & Trainor · 2005

Pregnancy onward · A moment for the family

Take a quiet moment together beneath slowly drifting colors.

Practice & research

Pause together beneath slow, organic ceiling patterns while the grown-ups settle into their own breathing. Keep your awake baby nearby and follow their cues. Return to a familiar guided pause when it fits your day.

An eight-week mindfulness and parenting course begun in pregnancy reduced self-reported stress at three months postpartum. It supports the parent-wellbeing approach; brief ceiling-guided sessions are our adaptation.

As they grow · Later-childhood concept

A planned listening game for later childhood: hear a chord and choose its color.

Practice & research

22 of 22 children who completed the study’s training acquired absolute pitch.

24 began at ages 2–6; two discontinued. The study used family-led piano and flag exercises over extended training and follow-up.

Our research commitment

Build on discovery.
Keep asking what’s possible.

We plan to partner with academic institutions and researchers to investigate how early musical experiences shape auditory abilities and brain development, and whether those changes last.

Which activities develop listening precision? At which ages, and with how much practice? What changes in brain function or structure accompany learning, and do they persist? We also want to understand whether benefits extend into language, learning and everyday life.

Music is our starting point. Our mission will keep us exploring other ways to support early development as the evidence grows.

Before you join us

A few things
you might wonder.

What is Bell, and who is it for?

Bell is the ceiling projector and sound system we’re developing for shared music experiences at home. The first release is planned for pregnancy through twelve months.

Is Bell available now?

Not yet. Bell is in development. Our free research guides and browser training games are available now, and you can subscribe to The Beat to follow the research and our progress.

How do we take part together?

Bell is being designed to support musical exchanges between you and your baby. Sing, tap or move gently with a shared cue, notice their response, then adjust, repeat or pause. You lead the interaction. Looking, listening and vocalizing can all be ways to participate. First-year experiences are unscored, awake exploration; your baby does not need to keep a beat or give a correct answer. During pregnancy, the parent takes part in the listening experience.

What research supports the approach?

Published research on early listening and musical training informs our approach. Bell’s developmental effects have not yet been established. We plan to partner with academic institutions to study which activities help, at which ages, and whether gains last.

How is privacy built into Bell?

Bell’s design calls for no camera and on-device audio processing. We’ll confirm the final hardware, privacy controls and any optional recording features before purchase. Browser games request microphone access only when an activity needs it.
