Description The wooden bodied MS Harp. The best known Richter harmonica. The excellent workmanship and typical sound characterize Hohner’s modern manufacturing of instruments. Diatonic harmonicas from Hohner convince by highest quality, excellent response and best tonal characteristics. These harmonicas, built according to the Richter-system, are in principle single tone instruments and can be recognized by their undivided air channels. They are usually simply called “Blues Harps”” and are very convenient as melody instruments for blues, rock, country and folk. The fact that they are single note instruments allows bending and overblowing of certain notes in order to create the typical, howling blues sound as well as the missing chromatic notes.
