Listening to music can be a deep and profound experience. It can induce different moods and states of being.
Also, science tells us that music has several benefits like, for example, lowering blood pressure, lowering heart rate and decreasing anxiety.
Listening to music also activates and engages multiple areas of your brain.
When you actually play an instrument that activity becomes more like a full-body workout for the brain.
Both playing and listening to music have a vast amount of positive effects on the mind and body. There are numerous practical applications to change people’s lives, many of which are yet to be applied.
Just like meditation in schools can help children’s development, so can music. Playing music can aid in literacy and improves academic results, and more active participation increases the benefit.
Studies show that students who played instruments in class improved neural processing compared to students who attended the music appreciation class.   
Music, and sound in general, is one of the most primal forms of communication. Singing, chanting and drumming as artistic expression may have occurred as early as 60 000 years ago. Rhythm and frequency is deeply engraved in our brains and neuroscience finds that both drumming and making melodies correlates with the biology and structure of our brains.  
When musicians play together their brainwaves are synchronized – they oscillate in tandem. This suggests that jamming can be a way of connecting with people on more levels than with just conversation. 
Studies have shown that practicing music can rewire the brain and increase the size of the brain’s hearing center. Musicians are often more accomplished at filtering out noise from the environment and isolate speech – some are even more proficient at detecting emotional cues in conversations.
Playing and listening to music can improve communication between the left and right hemispheres of the brain, a feat that may improve general communication skills. 
Another amazing potential of sound is through music therapy. Music therapy have a wide spectrum of uses and several studies have shown great results on children and adults with autism. 
Music therapy can bring people back to the present moment and aid their memory.   Chech out this heartwarming clip from the documentary “Alive Inside” where the Alzheimer’s patient Henry literally wakes up when introduced to his favorite music:
