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

    An experiment with music21 and pretty_midi: the same phrase with fingering, a slur, and a dynamic marking, exported to both MIDI and MusicXML. What survives in each format, with real figures.

    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.

    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 it's a great way to start programming)

    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.

    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.

    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.
