I work long hours at a very stressful job, and I wanted to find an inexpensive hobby that I could do at night and on the weekends. I sat down one night and thought about my options, and it became clear that I needed to play music. I already had a guitar, so it seemed logical to learn to play. I went online and found a program to help me learn, and it included instruction on the pentatonic scales. I had so much fun playing, and every day I went home and practiced. This has been a great way to relieve stress, and I’m having fun.
