TOKYO, Dec 18, 2025 – (JCN Newswire) – TANAKA MIRAI Lab., an in-house innovation organization of TANAKA PRECIOUS METAL GROUP Co., Ltd. (head office: Chuo-ku, Tokyo; Group CEO: Koichiro Tanaka), has co-created the musical work with Sound Wellness Lab, the sound research institute of Della Co., Ltd., a long-established label known for music that supports mental and physical well-being. The series features musical works composed entirely from the sounds of precious metals such as gold (Au), silver (Ag), and platinum (Pt). The fourth release in the series, “Precious Metal Orchestra – A Musical Voyage through the Sound of Precious Metals for Christmas” became available on major music streaming services on Friday, October 31, 2025, available exclusively in Japanese.
TANAKA has been advancing a transformation of its overall business toward the year 2085, the 200th anniversary of its founding, with the aim of “creating a bright future that no one has ever seen before.” As part of this initiative, TANAKA established the TANAKA MIRAI Lab., an organization dedicated to driving the creation of new paradigms for a better future—from emergence to realization—and has been pursuing a wide range of research and development activities.
As one of its research themes, TANAKA MIRAI Lab. has turned its focus to the “acoustic properties of precious metals”. With support from Della’s Sound Wellness Lab—which scientifically analyzes the physiological and psychological effects of sound on humans and produces musical works based on these insights—TANAKA MIRAI Lab. has been developing a unique series of musical compositions created solely from precious metal sounds since June 2025.
The fourth collaborative musical work in the series features a Christmas theme. The piece is composed entirely of shimmering sound sources created from real precious metals performing well-known and classic Christmas melodies, delivering an ‘illumination of sound’ that enriches and transforms any space. The sound design was led by composer Mitsuhiro, renowned for his many acclaimed healing-music works.
Going forward, we plan to further expand the range of precious metal sound sources and incorporate more diverse performance techniques, with the aim of establishing ‘precious metal sound’ as a new musical genre.
Composer Mitsuhiro’s Comment
The sound produced by pure precious metals is astonishingly clear. It extends with a pristine, unwavering purity—like the crisp air of an early winter morning—and that clarity is part of its unique appeal. In an era that values music capable of moving the heart through the power of simple, authentic sound, I hope these compositions will be enjoyed across many occasions, from celebrations such as weddings to in-store background music, or even as a musical gift accompanying something special for a loved one.
