Historically informed performance practice, contemporary music, 429 Hz tuning. Curated by an audio engineer and musician. FLAC up to 192 kHz.
An example.
The standard tuning pitch was not always 440 Hz. Verdi composed at 432 Hz. Baroque orchestras play at 415 Hz. Nikolaus Harnoncourt recorded Mozart in historical tunings – not out of nostalgia, but because the timbres change.
Mother Earth Klassik uses 429 Hz. A conscious decision between historical practice and modern tuning. Low enough for a relaxed, warm sound. High enough for presence and articulation.
This is no triviality. If Harnoncourt chose a different tuning for each era, he acknowledged what all musicians have known for centuries: tuning is not an add-on. Tuning is what music is made of.
