Charm of Gagaku
There are no galays in a shrine and chances to see only about a wedding before the altar in today. But the oldest music is Gagaku in Japan with history in 1400.
Only an Imperial Court (emperor) and an aristocrat are most conspicuous in the Heian Period and they’re the music ordinary people didn’t experience until the modernized world as something special in which you can participate more than ancient times.
But Japanese music of the “Samisen” “Koto” “Shakuhachi” “Shinobue” etc. inherited today (traditional Japanese music container) and a traditional entertainment of “Noh play” “fan” word” “kabuki” etc., the, everything makes the court music of Japan roots mostly.
