Description
Technical Field
The invention relates to the technical field of music equipment, in particular to a double-row thumb piano easy to play.
Background
The thumb musical instrument is a national musical instrument with national characteristics in Africa. In different african countries, the Thumb organ has different names, for example Kalimba is the name for this instrument in kennia, while in zimbabwe it is called Mbira, congo is called Likembe, and it has the names Sanza and Thumb Piano, etc. It is mainly named by using thumb to stir the thin sheet (mainly made of wood, bamboo and metal in modern development) on the body.
When the thumbs are used for playing the piano, the thumbs of the two hands are used for pressing the keys and then releasing the keys, and the sounds are made through vibration. The scales of the existing thumb musical instrument are generally orderly arranged, or the scales are orderly arranged from high-pitched to low-pitched, or the low-pitched is in the middle, and the going-to-high-pitched time is orderly distributed on the left side and the right side; the thumb piano of this type has the problems that the key spacing is too small to be easily touched by mistake or the musical scale with symmetrical distribution is slow in sound finding speed and difficult to synchronize with the melody during playing. Therefore, we propose a double-row easy-to-play thumb piano.
