Celtic Constellation
High-fidelity isolated bagpipe notes and articulations for modeling phrasing, ornamentation, and chanter behavior.
Structured at the articulation level using documented production workflows and secured under the Proteus Standard™.
The Great Highland Bagpipes are a mouthblown bagpipe featuring an open-ended chanter and a continuous airflow-driven sound production system, supplied by a combination of breath input and bag pressure. In this instrument, airflow is maintained through active breath control and arm pressure on the bag, producing a powerful, steady tone with limited dynamic range. Expressive control is achieved primarily through fingering technique, articulation timing, and precise management of airflow and pressure rather than changes in amplitude.
Acoustically, the Great Highland Bagpipes occupy a strong and distinctive timbral space characterized by sustained tone, pronounced harmonic content, and continuous sound output. Expressivity emerges through articulation patterns, gesture timing, and ornament-driven movement rather than abrupt shifts in loudness or tone color. Traditionally used in solo, ceremonial, and ensemble contexts, the instrument’s physical design and continuous airflow behavior make it well suited for articulation-level analysis and modeling, where clarity of note transitions, pressure consistency, and repeatable gesture behavior are critical.

An overview of what’s included in this dataset — from articulations and performance styles to session context and recording notes.
This preview dataset contains a curated subset of articulation-focused recordings from the Great Highland Bagpipes.
The material is intended to illustrate the dataset’s structural approach, capture quality, and articulation taxonomy, rather than represent the full scope of the final release.
Included recordings emphasize stable tone production, controlled note transitions, and representative melodic gestures characteristic of Highland bagpipe performance, captured in isolation to support expressive audio modeling, evaluation, and analysis workflows.
The full dataset will expand substantially on this foundation, with broader pitch coverage, a larger articulation set, and an extended corpus of recorded material reflecting the full expressive range of the instrument.
All audio was recorded in a controlled studio environment using standardized capture, editing, and QC protocols consistent across the Harmonic Frontier Audio catalog.
Source material was captured at 32-bit float to preserve full dynamic headroom and minimize quantization artifacts during editing and processing.
Final preview files are delivered as 24-bit PCM for consistency and downstream compatibility.
A single instrument was used consistently across all sessions to maintain timbral continuity and articulation stability.

Additional processing was limited to trimming, fade handling, and integrity checks. No creative processing, normalization, or dynamic shaping was applied beyond what was necessary for clean delivery.
A structured breakdown of the expressive building blocks in this dataset — including articulations, dynamics, transitions, and any extended techniques captured during recording.
Unlike clip- or phrase-based datasets, this dataset is structured at the articulation and gesture level. This enables interpretable control, expressive variability, and human-aligned modeling, but significantly increases production complexity and significantly limits who can produce such datasets correctly at scale.
This preview includes representative examples of core Highland bagpipe articulations, captured in isolation to support articulation-aware modeling and analysis.
Articulations include:
Articulations are recorded without accompaniment or rhythmic framing to preserve clarity, separability, and modeling utility.
The preview dataset includes limited examples of gesture-level behavior intended to demonstrate the structure of the full dataset rather than exhaustively cover all techniques.
Gesture types include:
More advanced ornamentation patterns, extended melodic figures, and performance-driven gestures will be included in the full dataset release.
A three-layer provenance and integrity framework ensuring verifiable chain-of-custody, tamper-evident delivery, and spectral fingerprinting for enterprise deployment. These layers are versioned and maintained to support long-term auditability, continuity, and enterprise compliance.
All full datasets from HFA include provenance metadata, session identifiers, and spectral integrity markers as part of The Proteus Standard™ for compliant enterprise deployment.
Captured with expert musicians and vocalists across global traditions — ensuring each dataset carries authentic nuance, human expression, and rights-managed provenance.
Blake Pullen is a multi-disciplinary musician, vocalist, and recording engineer with a background spanning traditional Celtic music, contemporary performance, and audio production.
With formal training in vocal performance and extensive experience recording acoustic instruments, Blake approaches dataset creation from both a musical and systems-oriented perspective. His work emphasizes articulation-level clarity, consistency across sessions, and recording practices designed to support long-term machine learning use rather than short-term musical presentation.
As the founder of Harmonic Frontier Audio, he performs and records the initial datasets to establish a consistent technical and musical foundation for the catalog, ensuring that capture methodology, articulation taxonomy, and provenance standards are applied rigorously from the outset.
A three-part listening benchmark: a mixed musical demo built from this dataset, the raw source clip, and an AI model’s attempt to reproduce the same prompt.
A musical demonstration created by replacing a state-of-the-art AI-generated lead instrument with original source recordings from this dataset, then arranged and mastered to preserve musical context. This approach allows direct comparison between current-generation model output and real, rights-cleared acoustic source material.
Directly from the dataset: an isolated, unprocessed example of the source recording.
