Playing Instrumental Music Neurological and Endocrine Effects
Playing instrumental music has important neurological and endocrine effects. In certain countries, playing an instrument is obligatory in schools.
Below is a comprehensive, evidence-based overview of the neurological and endocrine effects of playing instrumental music (e.g., piano, violin, drums, guitar).
Effects are strongest in trained musicians and those with active performance experience, but even amateur practice yields benefits.
Group effects (e.g., orchestra, band) are noted where applicable. Neurological Effects of Playing Instruments
Effects are strongest in trained musicians and those with active performance experience, but even amateur practice yields benefits.
Group effects (e.g., orchestra, band) are noted where applicable. Neurological Effects of Playing Instruments
- Neuroplasticity & Brain Structure
- ↑ Gray matter in motor, auditory, and visual cortices (Heschl’s gyrus, premotor cortex, corpus callosum) (Gaser & Schlaug, 2003; Hyde et al., 2009).
- ↑ White matter integrity in arcuate fasciculus and corticospinal tracts—stronger than in singers (Halwani et al., 2011).
- Corpus callosum enlargement: Up to 30% thicker in keyboard players (Schlaug et al., 1995).
- Motor & Multisensory Integration
- Bimanual coordination: Piano/drumming activates bilateral M1, SMA, cerebellum—superior to unilateral activities (Bangert & Schlaug, 2006).
- Audiomotor coupling: Real-time feedback loop between auditory cortex (A1) and motor cortex (M1) via arcuate fasciculus (Zatorre et al., 2007).
- Executive Function & Cognitive Reserve
- ↑ Working memory, attention, IQ: Musicians outperform non-musicians by 7–10 IQ points on average (Schellenberg, 2004).
- ↑ Cognitive flexibility & inhibition: Drummers show the fastest reaction times (Slater et al., 2017).
- Delayed cognitive decline: Lifelong instrumental practice linked to 5+ years delay in dementia onset (Wan & Schlaug, 2010).
- Emotional Regulation & Reward
- Dopamine release: Peak emotional moments (e.g., crescendo, improvisation) activate the nucleus accumbens (Salimpoor et al., 2011).
- Amygdala-prefrontal connectivity: Reduced anxiety via top-down control (Pantev et al., 2001).
- Autonomic & Vagal Effects
- ↑ Heart rate variability (HRV) during expressive playing (e.g., slow violin adagio) (Nakahara et al., 2010).
- Less than singing (no diaphragmatic dominance), but more than passive listening.
Endocrine Effects of Playing Instruments

Cortisol

↓ Post-performance
|
Solo or group
|
10–20% drop (less than singing/dancing) (Fancourt et al., 2016)
|
|
Oxytocin
|
↑ in ensemble
|
Orchestra, band
|
20–40% (lower than synchronized dance/singing) (Keeler et al., 2015)
|
|
β-Endorphins
|
↑ during flow state
|
Improvisation, mastery
|
Moderate (Dunbar et al., 2012 analog)
|
|
Testosterone
|
↑ in males during competitive performance
|
Jazz solo, drum battle
|
Acute spike (Schladt et al., 2017 analog)
|
|
SIgA (Immunity)
|
↑ slightly
|
Group rehearsal
|
+50–80% (weaker than singing) (Kreutz et al., 2004 analog)
|
Key: Endocrine effects are weaker than singing/dancing because no vocalization (↓ SIgA, ↓ vagal tone) and less full-body movement.

Special Strengths of Instrumental Music
|
Domain
|
Why Instrumental Wins
|
|---|---|
|
Fine Motor Precision
|
Piano/violin → best bimanual training (strongest M1 plasticity)
|
|
Multitasking Brain
|
Reading score + playing + listening → ultimate cognitive load
|
|
Long-Term IQ Boost
|
Only activity with causal IQ gains in children (Schellenberg, 2004)
|
|
Therapy
|
Music-based motor rehab (e.g., piano for stroke hand recovery)
|
Clinical & Practical Implications
- Stroke / TBI Rehab: Piano therapy restores hand function faster than PT alone (Schneider et al., 2007).
- ADHD / Autism: Drumming improves attention and social timing.
- Aging: Best for cognitive reserve among non-social music activities.
- Mental Health: Flow state in practice = mindfulness + achievement.
Bottom Line
Playing instruments is the ultimate brain gym for precision, multitasking, and long-term cognitive development.
It builds the most connected, efficient brain—but lacks the hormonal punch of singing (vagus/oxytocin) or dancing (oxytocin/movement).
Best combo? → Play in a band/orchestra (adds social hormones) or sing while playing (e.g., guitar + vocals).
