Practice, Practice Practice! But it's not only the time we spend practicing that makes us good at playing our instrument, but it's also the "how" we practice that matters!
When we play an instrument, our brain trains visual, auditory and motor skills, and simultaneously engages our emotions, an exceptional situation which can be described as a firework of the brain. There are different tips and tricks that make our practice more effective and fun. Such as Practicing a piece backward and many more.
