Two musical instruments were discovered at the Wakamiya shrine, an auxilliary shrine of the Kasuga Taisha of Nara. These two instruments, a
sho (mouth organ) and a
wagon (long zither) are believed to have been made in the latter half of the 12th century (the end of the Heian period).
The most interesting feature of the
sho is the presence of
byojo (rectangular finger-holes which determine pitch) on the reverse side of two of the bamboo pipes (
ya and
mo).
Byojo are also found on the 8th century
sho, found at the Shosoin, the imperial repository of Nara. The discovery of
byojo on a Heian period instrument challenges the general view that the use of
byojo had died out. Moreover, the Heian period instrument's
ya and
mo are tuned in almost perfect agreement to the
sho in the Shosoin.
Another notable characteristic is that the placement of finger holes is not in a horizontal line, but in a diagonal rising to the left, in this respect also mirroring the Shosoin instrument. From the latter half of the Heian period the placement of the finger holes is in a horizontal line as in modern instruments, thus the discovery of the Wakamiya
sho would indicate that the transition from diagonal to the horizontal placement occurred within the Heian period.
According to the Wakamiya shrine records of 1137 this
sho was an offering from Fujiwara Tadazane. However, markings on the instrument indicate that the
sho had been played prior to this dedication ceremony, indicating the
sho was made pre 1137. Parallels with the Shosoin
sho (specifically the pre sence of
byojo and the positioning of the finger holes), coupled with evidence of wear on the instrument, lead one to surmise that this instrument was made between the middle and the end of the Heian period. The lacquering used on the wind chamber (
ho) is representative of techniques used at the end of the Heian period and it shows no evidence of having been played prior to the ceremony. Therefore it was probably new at the time of the dedication. All of the bamboo pipes have the pitch name inscribed on them.
The most significant feature of the
wagon is that the end portion of the body does not have the usual six protuberances, but instead resembles flower petals, similar to the
wagon of the Shosoin. This indicates that the modern shape of the
wagon must have evolved after the Heian period. In addition, bark remains on part of the body of the instrument, as well as the nesting holes of insects that lived inside the tree from which it was made. As this kind of wood was not generally used for
wagon instruments it seems that there is significance behind its selection. Although there are signs that the instrument had strings there are no markings to suggest it was ever performed, thus it appears that it was made as an offering to the shrine.
The precise year the
wagon was made is unknown, however its presence appears in the records from the Kasuga Taisha of 1236, indicating that it was probably dedicated to Wakamiya sometime after the shrine was built (in 1135).
