Abstract

The utility model discloses a bass Gelonus which comprises a plurality of bamboo sound pipes lashed on a stand in rows. The ratio of the length of the bamboo sound pipe and the diameter of the upper end of the bamboo sound pipe ranges from 46:1 to 11:1. By adopting super-long bamboo sound pipe with the ratio of 46:1 of the length and the diameter of the upper end thereof, the range of the Gelonus increases by more than two octaves, thus meeting the requirement of bass by a band and the expression of the musical instrument can be enhanced.

Description

Bass Ge Longbu

Technical field

The utility model relates to a kind of musical instrument, especially surpasses the bass Ge Longbu of conventional Ge Longbu on range.

Background technology

In existing popular musical instrument, the bamboo musical instrument that a kind of Ge Longbu of being called is arranged, its structure be the different horizontal series arrangement of bamboo sound pipe of pitch on support, playing method is unique gas shock bamboo trunk mouth pronunciation of with the hands clapping the hands and producing, sound is full flexible again, is a kind of musical instrument that is rich in characteristics.But, Ge Longbu only has the high pitch musical instrument as popular musical instrument at present, its sound length of tube is between 75 centimetres to 28 centimetres, range at big word group G between the small character group c, still there is not the Ge Longbu that range is expanded to bass area, can't play out abundanter expressive force and better performing effect, and form the required bass part of band.The length of tubulose musical instrument sounding body the best, diameter ratio are 36: 1 or its multiple, length, the diameter ratio of general bamboo flute are about 18: 1, because bamboo natural material specification is limited, its playing method can not be too thick to the requirement in sound mouth of pipe footpath, so nobody produces the Ge Longbu of bass at present.

The utility model content

In order to make Ge Long be furnished with wide in range range, increase expressive force and better performing effect, and the required low part musical instrument of composition band, the utility model provides a kind of range of sound to be lower than the above bass of two octaves of present conventional Ge Longbu, breaks through the conventional ratio of tubulose musical instrument internal diameter and pipe range and obtains a kind of tone color of uniqueness.

Bass Ge Longbu described in the utility model comprises a plurality of bamboo sound pipe of colligation in a row in the qin frame, and the length of described bamboo sound pipe is 46: 1 to 11: 1 with the scope of the ratio of its upper end diameter.

Bass Ge Longbu described in the utility model, according to the principle that the length of air sound column vibrations in the sounding body is directly proportional with its pitch that is sent, employing overlength sound pipe makes its double bass can reach two groups of big words below the G.Break through the conventional ratio of tubulose musical instrument internal diameter and pipe range, the harmonic wave reason of elongated sound pipe air column vibrations during owing to pronunciation obtains a kind of tone color of uniqueness.Adopt socket to connect at the middle part of overlength sound pipe, make the sound pipe of overlength become two sections, plug and unplug connection with socket, the scalable pitch, and convenient transportation is used.The sound pipe by the colligation of length series arrangement, is placed on the qin frame.

The beneficial effects of the utility model are: break through the present situation that present Ge Longbu only has the high pitch musical instrument, use overlength sound pipe, make the range of Ge Longbu increase by two more than the octave, because the sound pipe is elongated, broken through the conventional ratio of tubulose musical instrument internal diameter and pipe range, thereby obtain a kind of tone color of uniqueness, to satisfy band to the demand of bass part musical instrument and enrich the expressive force of this kind musical instrument.

Embodiment

Below in conjunction with accompanying drawing bass Ge Longbu described in the utility model is described further.

As shown in Figure 1, 2, 3, among the utility model embodiment, pronunciation sound pipe 1 is taken upper end diameter and is not more than 8 centimetres thin sound pipe, to be suitable for the hands the clap the hands playing method of the gas shock bamboo trunk mouth pronunciation that produces of this musical instrument, the sound length of tube then uses the long sound pipe of length according to the pitch of required sound pipe, though this design is different from the proportional law of conventional sound pipe 36: 1 or its multiple, and reach 46: 1, but because its sound pipe overlength and the range of sound is extended downward to reach the G of two groups of big words.The vibrations of air column obtained a kind of tone color of uniqueness owing to the harmonic wave reason when simultaneously elongated sound pipe pronounced, and the range of sound also reduces greatly.Its diatonic scale is 18 sound pipes, and variation sound is 12 sound pipes, and double bass sound length of tube is 3.66 meters, 8 centimetres of upper end diameter, and just the length of its sound pipe is 45.75: 1 with the ratio of its upper end diameter, approaches aforesaid 46: 1, pitch is two groups of G of big word; Descant sound length of tube is 66 centimetres, and upper end diameter is 6 centimetres, and the length of its sound pipe is 11: 1 with the ratio of its upper end diameter, and pitch is big word group C.In an octave of bass area, because the sound pipe is long, the Yu Yinguan middle part is provided with and links socket 2, and detachable assembling is used with convenient transportation, and the scalable pitch.The height order that the sound pipe is pressed pitch horizontally, the sound pipe upper end mouth of pipe is arranged in straight line, 80 centimetres on distance ground, for the player implements to play end, end distance ground is 18 centimetres under the long pipe, arrange the good effective rope colligation of sound and in a row place on the qin frame 4, four posts of qin frame 4 are provided with castor 5, and convenient moving used.

Claims

1. a bass Ge Longbu comprises a plurality of bamboo sound pipe of colligation in a row in the qin frame, it is characterized in that: the length of described bamboo sound pipe is 46: 1 to 11: 1 with the scope of the ratio of its upper end diameter.

2. bass Ge Longbu as claimed in claim 1 is characterized in that, described bamboo trunk middle part is provided with the connection socket.
