+# Harmonic Frontier Audio – Kalimba (Preview, v0.9)
+
+**A high-fidelity world instrument dataset designed for AI training, music research, and creative sound development.**
+
+**Kalimba (Preview)**, created by **Harmonic Frontier Audio**, provides a compact reference set demonstrating the quality, formatting, and metadata conventions used in the *World Resonance Gallery* in the Harmonic Frontier Audio catalogue.
+
+---
+
+### 🔎 Summary
+
+This dataset offers high-quality, rights-cleared recordings of the **Kalimba** — a plucked idiophone of African origin, also known as the **thumb piano** or **Mbira**.  
+The recordings capture the unique metallic resonance of the instrument’s tines and the warm body tone that follows each strike, making it valuable for **AI music modeling**, **acoustic analysis**, and **cross-cultural sound synthesis** research.
+
+Developed by **Harmonic Frontier Audio**, this collection follows *The Proteus Standard™* for dataset provenance, transparency, and ethical AI use.  
+It provides researchers, developers, and sound designers with clean, consistent audio files that demonstrate the Kalimba’s percussive clarity, sustained decay, and expressive dyadic and arpeggiated gestures.
+
+If you find this dataset useful, please consider giving it a 🤍 on Hugging Face to help others discover it.
+
+---
+
+## 🎶 About the Kalimba
+
+The **Kalimba** is a lamellaphone from the Mbira family of instruments, originating in sub-Saharan Africa.  
+It consists of metal tines attached to a resonating wooden body, played by plucking the tines with the thumbs.  
+The sound is at once percussive and melodic — metallic transients followed by rich resonant decay.  
+
+Kalimbas are often tuned to diatonic or pentatonic scales, though alternate tunings exist across African regions.  
+This preview dataset was recorded on a **17-key C major Kalimba**, offering single-note, dyadic, and arpeggiated gestures across the full playable range.  
+The goal was to capture the instrument’s core articulations neutrally — not tied to any specific cultural or stylistic context — providing universal training material for AI and creative sound development.

+
+## 🎤 Recording Notes
+
+- Recorded in a treated studio environment using a **dual-mic setup** blended to mono:  
+  - **Front Mic (transients):** Oktava MK-012 (small-diaphragm condenser), 8″ above the tines  
+  - **Rear Mic (resonance):** RØDE NT1-A (large-diaphragm condenser), 6″ behind the sound holes  
+  - **Recording chain:** Oktava MK-012 + RØDE NT1-A → Zoom F8n Pro  
+- Captured at **96 kHz / 32-bit float**, rendered as **96 kHz / 24-bit** mono WAV for release.  
+- Transient integrity preserved; minor ambient noise retained for natural realism.
