Music to Code By
"Carl Franklin chose 25 minutes to coincide with the Pomodoro Technique of time management, popular with developers today. He also chose a "groove chill" approach. Real instruments combined in loops with melodic licks placed on top. The pieces change enough to not be boring, but not so much as to demand your attention. The first piece, Blue, is at 60 BPM (beats per minute) and the other two, Orange and Yellow, are at 80 BPM. According to research, music between 50 and 80 BPM is perfect for helping you focus, letting your brain generate those wonderful alpha waves."
