What is the difference between harmonica music and flute music?

There are two kinds of music scores commonly used in today's music industry: simple notation and staff notation, which are vividly called digital notation and tadpole notation. Almost all musical instruments can use these two kinds of music scores, and harmonica and flute are no exception. In this respect, there is no difference in their music scores.

On the other hand, the harmonica has a special musical score called BD score, which uses numbers with letters B and D to indicate the pitch level. For example, 4B means playing in the fourth hole and 5D means listening in the fifth hole. However, harmonicas are also classified. 10 hole harmonica (blues and blues) and chromatic harmonica, each hole has two notes, and BD spectrum can be used. The polyphonic harmonica has only one sound per hole, which is not suitable for BD spectrum.

Summary: The commonly used music score and staff are suitable for almost all musical instruments. The harmonica has its own BD symbol, just as the guitar has its own staff symbol. But in the final analysis, this exclusive notation is only for beginners to be familiar with fingering, keys and so on. If you want to pursue further studies, this exclusive notation will be abandoned sooner or later.
