Meditation typically requires you to focus on your breath with your eyes shut. When thoughts come to you, it's often recommended you take notice of these thoughts and gently come back to the breath. Instead of using the breath, you can meditate on the sound of intervals and learn to recognize the most important intervals in music. Listen to these playlists while you meditate, sleep, work, or take care of errands. These simple exercises can dramatically increase your ability to recognize intervals and get away from writing at the keyboard or notation program.
