The Cognitive Benefits of Music Lessons in Enhancing IQ

We do see it all the time, children who excel in the classroom also seem to be very gifted with musical instruments. So, do music lessons really enhance your IQ? Let’s go for an academic exploration around this…

The influence of music education on cognitive development has been a subject of considerable interest and research. Particularly, the association between music lessons and enhancement of Intelligence Quotient (IQ) has garnered attention due to its implications for educational policies and practices. This academic discussion delves into the cognitive benefits of music lessons in enhancing IQ, considering the underlying mechanisms and implications.

Cognitive Processes Impacted by Music Lessons:

We understand that music lessons require certain cognitive strengths, lets break this down into the greater benefits…

  1. Executive Functions: Music education demands the coordination of various cognitive processes, including attention, working memory, and inhibitory control. These executive functions are essential for problem-solving, planning, and decision-making, contributing to overall intellectual development.

  2. Pattern Recognition: Music involves complex patterns of rhythm, melody, and harmony. Regular exposure to such intricate patterns through music lessons enhances pattern recognition skills, which are transferable to other domains requiring analytical thinking.

  3. Auditory Processing: Musical training hones auditory discrimination, aiding in the differentiation of various tones and sounds. This refined auditory processing can lead to improved language skills, as language itself relies on the perception of distinct auditory cues.

  4. Memory Capacity: Music education often involves memorizing compositions. This practice augments both short-term and long-term memory capacities, strengthening memory recall abilities applicable across disciplines.

Mechanisms Underlying IQ Enhancement:

Taking the above into account how then does help in IQ enhancement, or in basic terms helps a child learn better? Four beneficial learning skills are unintentionally coached through the learning and practice of playing an instrument, let’s take a closer look…

  1. Neuroplasticity: Music learning triggers neuroplastic changes in the brain. The brain adapts its structure and function in response to new experiences, a phenomenon crucial for learning and intellectual growth.

  2. Cross-Domain Transfer: The cognitive skills honed through music education can extend beyond the realm of music itself. For instance, enhanced auditory processing might lead to improved reading skills, as reading also requires auditory discrimination.

  3. Enhanced Connectivity: Playing an instrument necessitates fine motor skills, hand-eye coordination, and simultaneous engagement of multiple brain regions. This complex coordination strengthens interconnectivity among brain areas, potentially enhancing cognitive efficiency.

  4. Emotional Engagement: Music invokes emotional responses, engaging the limbic system. Emotional engagement fosters deeper cognitive processing and memory consolidation, further contributing to cognitive development.

Research Evidence:

I did suggest in my introduction that we would take an academic dive into this, the following four studies a prominent in this area and worth taking a further look if you want to explore more in depth around this…

  1. Rauscher et al. (1997): The 'Mozart Effect' study suggested that listening to Mozart's music could temporarily enhance spatial-temporal reasoning. Although this effect's magnitude and duration were debated, it spurred research into music's cognitive impacts.

  2. Schellenberg (2004): A study found that children enrolled in music lessons exhibited greater IQ gains than those in drama or no extracurricular activities. The group engaged in music lessons displayed enhanced cognitive abilities in non-musical domains.

  3. Hanna-Pladdy & Mackay (2011): This study revealed that musicians outperformed non-musicians on cognitive tasks involving executive functions, memory, and information processing speed.

  4. Correlation vs. Causation: While correlations between music education and cognitive benefits are evident, establishing causation is complex due to potential confounding variables. Socioeconomic status, parental involvement, and pre-existing cognitive abilities can influence both musical engagement and cognitive development.

Educational Implications:

Before we wrap up I will be bold and make some suggestions on the benefits of this in educational settings…

  1. Integration into Curriculum: Incorporating music education into the academic curriculum could leverage its cognitive advantages to enhance students' overall intellectual growth.

  2. Early Intervention: Early exposure to music lessons might yield more pronounced cognitive benefits, as brain plasticity is higher during childhood.

  3. Interdisciplinary Approach: Recognizing the cross-domain transfer of cognitive skills developed through music, educators can design curricula that foster synergies between music and other subjects.


To conclude, research indicates a promising relationship between music lessons and enhancement of IQ-related cognitive processes. The cognitive demands of music education, coupled with neuroplastic changes and cross-domain transfer mechanisms, contribute to this phenomenon. While correlations are evident, rigorous longitudinal studies are needed to establish causation unequivocally. The educational sector can leverage these findings to design holistic curricula that foster cognitive development through music, thereby nurturing well-rounded individuals poised for academic and intellectual success.
