Is known as 10-hole Richter Tuned Harmonica the world over except in USA' where it is called 'blues harp' or tin sandwich', and is becoming the most widely known type of harmonica (except in asia where the tremolo is by far the most popular among the billions).("Tremolo harmonicas are perhaps the most common form of harmonica in the world, being very popular in folk music as well as in much of East Asia. In the West, the tremolo harmonica is usually encountered in traditional folk music, being found throughout Europe and South America in this role. In China, Japan, Korea, Taiwan and other parts of Asia, however, tremolo harmonicas are found in nearly every area of music from folk to classical — in fact, there are specially manufactured tremolo harmonicas for ensemble playing. Players often use several different harmonicas at a time, holding them one atop the other, in order to play notes and chords not available on any single instrument.:). ........................................
There are numerous techniques available for harmonica, including bending, overbending, and tongue blocking.
In addition to the 19 (draw 2 and blow 3 are the same pitch even though there are 10 holes) notes readily available on the diatonic harmonica, players can play other notes by adjusting their embouchure and forcing the reed to resonate at a different pitch. Although it is notoriously difficult and can be frustrating for beginners, one does this by relaxing and coordinating muscles in the throat, mouth, and lips. This technique is called "bending", a term borrowed from guitarists, who literally "bend" a string in order to create changes in pitch. Using bending, a player can reach all the notes on the chromatic scale. "Bending" also creates the glissando characteristic of much blues harp and country harmonica playing. Bending on a guitar bends the pitch upward. However, typically "bending" on a harmonica means the pitch falls downward. Bends are essential for most blues and rock harmonica due to the soulful sounds the instrument can bring out. The famous "wail" of the blues harp typically required bending.
