Description

Sleeper bilayer key thumb piano

Technical field

The present invention relates to musical instruments technical field, especially a kind of improved thumb piano.

Background technique

Thumb piano is a kind of traditional instrument from Africa, generally comprises resonant tank, wooden rectangular backing plate and 1-2 row's band bullet The steel disc of property.Bimanual thumb is pressed steel disc and is decontroled again, is made a sound by vibration.Existing thumb piano is one layer of steel disc Key, scale are symmetrically arranged, and bass is sequentially distributed when walking toward high pitch in the right and left in centre, scale.Steel disc key is held on It is intermediate to be fixed on sheeting caps or resonant tank with metal bead pushing steel disc key on wooden nut.Existing thumb piano steel disc Key number is 5 keys, 10 keys, 15 keys, 17 keys.There are key spacing too small easy accidentally touching, scales to lack many music for such thumb piano It is unable to complete performance, symmetrical scale looks for velocity of sound degree is slow, is difficult to harmony melody to synchronize the problem of carrying out.

Utility model content

In order to overcome the too small easy accidentally touching of prior art key spacing, scale to lack many music and be unable to complete performance, left and right Symmetrical scale looks for that velocity of sound degree is slow, is difficult to harmony melody synchronous the problem of carrying out, and the utility model provides a kind of double-deck sequence and arranges The thumb piano of column scale.

The technical scheme adopted by the utility model to solve the technical problem is as follows: on key frame, from left to right successively from Bass installs upper layer and lower layer steel disc key to high pitch, and key frame is fixed on resonant tank with self-tapping screw and glue.

Above-mentioned key frame is made of pressing member, L shape part, preceding sleeper, rear sleeper, round steel filler strip, pressing member, L shape part and Sleeper has key hole to make installation limit afterwards.

Two layers above-mentioned of steel disc key, sum are 20 or 34.

When two layers above-mentioned of steel disc key sum is 20, upper and lower level respectively installs 10, lower layer's key from left to right scale It puts in order as A3, C4, E4, G4, B4, D5, F5, A5, C6, E6 in international acoustics pitch notation, i.e. C tune numbered musical notation pitch mark In bass 6,1,3,5,7, high pitch 2, high pitch 4, high pitch 6, times high pitch 1, times high pitch 3；From left to right scale arranges upper layer key Sequence is G3, B3, D4, F4, A4, C5, E5, G5, B5, D6 in international acoustics pitch notation, i.e., in C tune numbered musical notation pitch mark Bass 5, bass 7,2,4,6, high pitch 1, high pitch 3, high pitch 5, high pitch 7, times high pitch 2.

When two layers above-mentioned of steel disc key sum is 34, lower layer installs 20, and from left to right scale puts in order as state G3, A3, B3, C4, D4, E4, F4, G4, A4, B4, C5, D5, E5, F5, G5, A5, B5, C6, D6 in the acoustics pitch notation of border, E6, i.e., bass 5, bass 6, bass 7,1,2,3,4,5,6,7, high pitch 1, high pitch 2, high pitch 3, height in C tune numbered musical notation pitch mark Sound 4, high pitch 5, high pitch 6, high pitch 7, times high pitch 1, times high pitch 2, times high pitch 3；Upper layer installs 14, and from left to right scale arrangement is suitable #G3, #A3, #C4, #D4, #F4, #G4, #A4, #C5, #D5, #F5, #G5, #A5, #C6, # in the acoustics pitch notation of the world Xu Wei D6；Bass #5, bass #6, #1, #2, #4, #5, #6, high pitch #1, high pitch #2, high pitch #4, height i.e. in C tune numbered musical notation pitch mark Sound #5, high pitch #6, times high pitch #1, times high pitch #2.

Above-mentioned upper layer steel disc key is made to retreat installation, and making it not influences lower layer's performance.

Two layers above-mentioned of steel disc key, by pitch marked in steel disc key close to one end that finger is stirred.

The utility model has the beneficial effects that the spacing of same layer key is not easy accidentally to touch more greatly after being divided into two layers of key, Several 20 keys of key or 34 keys, which obtain wider array of range, can play more music, and from left to right tactic scale logic is clear Clear, pitch mark looks for sound more rapidly close to one end that finger is stirred, and right-hand man forms clarification in certain roles when playing, and melody is easy with harmony It is carried out in synchronous.
