I write down what I'm learning as I research: automatic music transcription, signal analysis, digital lutherie.

    Rhythm games: music as the conductor of training

    Stage Tour announces RedOctane's return. The announcement is the hook; the underlying idea —music as the conductor of a training system— predates five buttons.

    Gaita Hero and EMTI Fervienza: evaluating the sound

    In 2011 I designed a system to check Asturian bagpipe scores. I'm still pulling the same thread: comparing a performance against a reference is an MIR problem.

    Python for music: librosa, music21, and pretty_midi

    One language, three separate toolboxes: librosa looks at the audio, music21 at the score, and pretty_midi at MIDI. What each library does and when to use it.

    Asturian bagpipe organology as data

    How the Asturian bagpipe can be described in measurable terms — parts, key, and frequency range — and what you need to understand before digitising it.

    MIDI vs MusicXML in Python: what survives and what doesn't

    An experiment with music21 and pretty_midi: the same phrase exported to MIDI and MusicXML. What survives in each format, with real figures.

    Data sovereignty: from principles to architecture

    How the GDPR, the AI Act and the Digital Bond Manifesto translate into technical decisions: no analytics, no cookies, with an explicit legal basis.

    What Music Information Retrieval (MIR) is

    The field behind automatic transcription, chord recognition, and Shazam. What MIR is and how MIDI, MusicXML, and AMT fit into it.

    AI as a tool, not as the final product

    Why I see generative AI as a tool that amplifies what you already know, not a substitute for judgment. With real data, not hype.

    How to compute a spectrogram with librosa

    A step-by-step tutorial, with a downloadable notebook, on going from real audio to its spectrogram with librosa: STFT, decibels, and reading harmonic bands.

    What MusicXML is: the score as data

    Moving a score between programs without it falling apart seems trivial, and it is not. What MusicXML is and how it differs from MIDI.

    What automatic music transcription is

    Turning a recording into a score sounds trivial until you try it. What automatic music transcription (AMT) is and why it remains an open problem.

    What a Jupyter notebook is and why to start with it

    A Jupyter notebook blends explanation and runnable code in one document. What it is and why I think it's a great way into programming, especially for teaching.

    openDAW: an open-source DAW that lives in the browser

    What openDAW is, how it runs in the browser via the Web Audio API and TypeScript, and how its data sovereignty model connects with GDPR and free software.

    How to build an audio corpus for music research

    An audio corpus is not a playlist: it is a structured, labelled, reproducible collection. What it takes to make one genuinely useful for MIR research.

    Making music with Arduino: from buzzer to MIDI

    How to get sound out of an Arduino, from a buzzer with tone() to turning sensors into controllers. A practical walkthrough, no expensive hardware.

    The Fourier transform: from time to frequency

    Why sound can be understood as a sum of frequencies, what the Fourier transform does with that idea, and how it explains the spectrum.

    What MIDI is: instructions, not audio

    What MIDI is and, more importantly, what it is not. How a MIDI message describes a note without audio, and why that makes it so flexible.
