+# Harmonic Frontier Audio – Kazoo (Preview, v0.9)
+
+**A high-fidelity acoustic dataset designed for AI training, music research, and creative sound development.**
+
+**Kazoo (Preview)**, created by **Harmonic Frontier Audio**, provides a compact reference set demonstrating the quality, formatting, and metadata conventions used in the *Novelty Gems Cabinet* of the Harmonic Frontier Audio catalogue.
+
+---
+
+### 🔎 Summary
+
+This dataset provides high-quality, rights-cleared recordings of the **Kazoo** — a buzzing membranophone whose timbre is shaped by vocal input passing through a vibrating membrane.  
+The recordings highlight the instrument’s distinct nasal resonance, rapid transient response, and expressive harmonic coloration, making it valuable for **AI music modeling**, **timbre classification**, **acoustic analysis**, and **cross-cultural sound synthesis** research.
+
+Developed by **Harmonic Frontier Audio**, this preview follows *The Proteus Standard™* for dataset provenance, transparency, and ethical AI use.  
+It offers clean, consistent audio files that capture the Kazoo’s playful yet harmonically rich character across sustained tones, triads, glissandi, and articulation patterns.
+
+If you find this dataset useful, please consider giving it a 🤍 on Hugging Face to help others discover it.
+
+---
+
+## 🎶 About the Kazoo
+
+The **Kazoo** is a buzzing aerophone / membranophone most commonly used in folk, novelty, and participatory musical settings.  
+Its sound is produced when the performer vocalizes into the instrument, causing a membrane to vibrate and impart a distinctive **buzzing, nasally-modulated character**.
+
+Though simple in construction, the Kazoo is capable of surprising expressive range — from smooth glissandi to highly articulated tongued gestures.  
+This preview dataset was designed to capture the instrument’s **core articulations neutrally**, without stylistic coloration, offering a universal training source for AI and research applications.
+
+---
+
+## 📂 Contents
+
+### **Audio Files (.wav)**

+- Exported as **mono**  
+- Fade-ins and fade-outs of **3–5 ms** for transient consistency  
+- DC offset checked — **none detected**  
+- High-pass filtered at ~40 Hz to reduce subsonic rumble  
+- No EQ, compression, saturation, or post-processing applied
+
+### **Categories in this Preview**
+1. **Sustain**  
+   - Single sustained tones across multiple pitches  
+   - Includes vibrato and non-vibrato variations  
+
+2. **Glissando**  
+   - Smooth pitch slides (e.g., E→E, G→G) demonstrating membrane continuity  
+
+3. **Tonguing / Articulation**  
+   - Short, percussive bursts with distinct transient character  
+
+4. **Triads (Staccato)**  
+   - Rapid three-note sequences created through vocalized changes  
+   - Includes C–E–G, F–A–C, G–B–D patterns
+
+---
+
+## **Metadata (.csv)**  
+Includes structured fields for file name, category, articulation, note pitch, vibrato status, microphone used, channel configuration, sample rate, bit depth, recording chain, and dataset version.
+
+Metadata was hand-verified for consistency and accuracy according to Harmonic Frontier Audio standards.
+
+---
+
+## 🎤 Recording Notes
+
+- Recorded in a treated studio environment with:  
+  - **Microphone:** RØDE NT1-A (large-diaphragm condenser)  
+  - Positioned 8–10″ from the instrument for balanced capture  
+- Recording chain:  
+  **RØDE NT1-A → Zoom F8n Pro (32-bit float capture)**  
+  Exported as **96 kHz / 24-bit mono WAV** for release  
+- No noise reduction or dynamic processing used — transient integrity preserved  
+- Natural dynamics retained for realistic ML training behavior
