As music can absorb our attention, it acts as a distraction at the same time it helps to explore emotions. This means it can be a great aid to meditation, helping to prevent the mind wandering.
Musical preference varies widely between individuals, so only you can decide what you like and what is suitable for each mood. But even if you don’t usually listen to classical music it may be worth giving it a try when selecting the most calming music.
When people are very stressed, there is a tendency to avoid actively listening to music. Perhaps it feels like a waste of time, not helping to achieve anything. But as we know, productivity increases when stress is reduced, so this is another area where you can gain vast rewards. It just takes a small effort to begin with.
