01 / THE IDEA

Music genre classification in practice.

Music-genre classification maps short audio clips to genre labels using features that capture timbre, rhythm and spectral content. Important challenges include polyphonic mixtures, varying recording quality, overlapping genres, label noise and class imbalance.

Real-world use case · Proposed extension

A proposed application: assist curators or streaming services by pre-tagging tracks to speed manual curation; human editors should review and correct tags before they affect user-facing recommendations.

02 / THE BUILD

How to build a music genre classification project
step by step.

01

Collect and label audio

Assemble short clips with reliable genre labels and keep separate holdout sets to measure generalisation across artists and recording conditions.

02

Extract domain features

Compute mel-spectrograms, MFCCs and tempo/rhythm features from audio at a consistent sample rate and normalise across clips.

03

Train a baseline model

Fit a simple classifier (e.g. random forest or CNN) with cross-validation and track per-class precision, recall and macro F1.

04

Evaluate and inspect errors

Report confusion matrices, per-genre errors and failure modes such as mixed-genre clips and low-SNR audio.

03 / SOURCE SNAPSHOT

What the music genre classification starter actually does.

The supplied starter synthesises single-tone audio clips at two centre frequencies, computes a simple FFT-based feature vector (mean, std, argmax, 95th percentile of the spectrum), then trains a RandomForestClassifier to separate the two synthetic frequency classes and prints a classification report.

SOURCE EXCERPTPython
def synth_clip(freq, label):
    t = np.linspace(0, 1, sample_rate, endpoint=False)
    signal = np.sin(2 * np.pi * freq * t) + 0.05 * rng.normal(size=sample_rate)
    spectrum = np.abs(np.fft.rfft(signal))
    features = [
        spectrum.mean(),
        spectrum.std(),
        spectrum.argmax(),
        np.percentile(spectrum, 95),
    ]
Important limitation

The starter does not use music or genre labels. It creates sine-wave signals with noise and extracts simple spectral summary statistics; this only demonstrates a toy frequency-discrimination baseline, not real music-genre modelling. The dataset is tiny, synthetic and not representative of genre variation.

Where a music genre classification project could go next.

PROPOSED BUSINESS CONCEPT

Music Genre Classifier: a pilot concept

Proposed extension: replace synthetic clips with a labelled music dataset, extract mel-spectrograms and MFCCs, train a CNN or a feature-based classifier, and provide a human-review UI for ambiguous tags.

WHO IT COULD SERVEMusic curators and streaming editors
FIRST MVPA prototype service that tags short licensed clips with probable genres, shows confidence scores, and allows human editors to accept or correct tags.
KEY RISKHigh risk of mislabelling mixed-genre or poorly recorded tracks; any production use should keep a human reviewer in the loop and avoid automatic decisions that affect royalties or rights.

This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.

05 / WHAT YOU TAKE AWAY

What a music genre classification project puts on your resume.

  • Understand the difference between toy audio synthesis and real music data and why representative datasets matter.
  • Extract basic spectral features (FFT summaries, percentiles) and reason about their limitations for genre tasks.
  • Train and evaluate a baseline classifier and inspect confusion matrices and per-class metrics such as macro F1.
  • Plan a realistic extension: collect labelled music, extract mel-spectrograms/MFCCs, and add human-in-the-loop review.

06 / QUESTIONS STUDENTS ASK

Music Genre Classification project FAQs.

Is this suitable as a final year project?
Yes — it is an advanced audio and speech processing topic with scope for feature engineering, modelling and evaluation; suitable if you plan substantial work on datasets, architectures and experiments.
What skills or tools will I need to complete it?
You should be comfortable with Python, NumPy, scikit-learn and audio libraries (librosa), plus basics of signal processing, feature extraction (MFCCs, spectral features) and machine learning evaluation.
How should I evaluate progress and how long will it take?
Start by extracting robust features and building baseline classifiers, then iterate with better representations and handling imbalance; expect a few months of work for a solid project including experiments and report.
