This is a set of seven SESSION Standard harmonicas. The SESSION Standard is a diatonic harp with plastic comb and stainless steel covers - available in keys from LD to HA. If you are a beginner, you should be aware that this is the mother of all tunings, the so called 'Richter-Tuning'. The ingenious finding of the 'Diatonic Harmonica.' The keys in this set are the most commonly used keys: G, A, Bb, C, D, F, LD. This item also comes with a soft case. Richter is said to be descended from the Bohemian area east of Klingenthal from a town called Haida. It's not really proven, however it is fact that the 'Richter Harmonica' was initially called 'Haidaer' by a Seydel employee since the beginning of its production more than hundred years ago. The only important thing is that you cannot fail when you start the adventure of playing harmonica with this tuning. Almost every great player has begun with it. With the emphasis on blow notes you start to play folk music within five minutes, if you take the draw you start to dive into the magic of Blues and Rock'n Roll.
