In "Garden Rain" (1974, for brass ensemble), the limited and pitch-specific harmonic vocabulary of the Japanese mouth organ, the "shō" (see ex. 3), and its specific timbres, are clearly emulated in Takemitsu's writing for brass instruments; even similarities of performance practice can be seen, (the players are often required to hold notes to the limit of their breath capacity). In "A Flock Descends into the Pentagonal Garden", the characteristic timbres of the "shō" and its chords (several of which are simultaneous soundings of traditional Japanese pentatonic scales) are emulated in the opening held chords of the wind instruments (the first chord is in fact an exact transposition of the "shō's" chord, Jū (i); see ex. 3); meanwhile a solo oboe is assigned a melodic line that is similarly reminiscent of the lines played by the "hichiriki" in "gagaku" ensembles.
