Harmonicas are amazing instruments. At first people assume them to be like toys (you can buy really cheap ones everywhere) and initially the concept seems really easy: 10 holes, drawing air produces some notes and blowing air produces other notes. But the more you get into it, the more amazing it gets. Soon you discover that you can bend notes by positioning your tongue in a specific way and your repertoire increases tremendously. You learn about overbending, tongue blocking, the "Wawa" sound you make covering the flow of the air with your hand rhythmically (don't remember if that has a name)...

I knew very little about music when I decided to play the harmonica. I looked for an instrument that required little maintenance, were easy to transport and easy to play everywhere. So I decided to learn to play the harmonica by myself. It's easy to start with it, but it gets challenging when you try to learn those techniques mostly because you can't see inside people's mouths to see what they are doing and you aren't used to force your tongue to do those specific movements. When you see what people can do with it, it can be jaw dropping. I'm still a beginner at it but it's so rewarding after practising a lot to get your first bending, to reproduce songs you have learned just by muscle memory, to sound a little bit closer to those blues masters... definitely something worth to try in my opinion.
