| Stage | Algorithm | Output | |-------|-----------|--------| | 1. Pitch Tracking | CREPE (Convolutional Recurrent‑Encoder for Pitch Estimation) – 100 Hz resolution. | Pitch‑contour per frame. | | 2. Segmentation | Bayesian Change‑Point Detection on pitch & energy → candidate phrase boundaries. | start_ms, end_ms. | | 3. Shape Classification | CNN on normalized pitch vectors → categories ascending, descending, arch, zig‑zag, static. | shape. | | 4. Intensity Estimation | RMS + spectral flux → dynamic level (p, mp, mf, f). | intensity. | | 5. Anchor Detection | Signal‑processing heuristics (zero‑crossing rate, pitch‑modulation) for vibrato, bends, slides. | anchor_points. | | 6. Semantic Labelling | Transformer‑based sequence tagger trained on a curated corpus of 250 k human‑annotated marks. | type, metadata. |

The pipeline runs asynchronously in a Kubernetes job; results are cached for 24 h and become editable by the content creator.

  • Add Metadata – free‑text description, tags, and cross‑links (lesson, chord chart, external article).
  • Save – the JSON is persisted, and the mark instantly appears for viewers.
  • Tip – Use the “Batch Apply” button to propagate a motif across multiple occurrences automatically. mat6tube melody marks

    | Year | Milestone | Relevance to Melody Marks | |------|-----------|---------------------------| | 2015 | Mat6Tube launched as a video‑hosting platform for guitar tabs. | Early demand for “visual tabs” sowed the seed for richer notation. | | 2017 | Introduction of WaveSync – a timeline‑synchronized waveform viewer. | Provided the low‑level visual canvas for later Melody Marks. | | 2019 | Partnership with MuseScore to import MusicXML. | Opened the door for structured musical data alongside audio. | | 2021 | Release of AI‑Melodic Analyzer (deep‑learning model trained on 1.2 M annotated phrases). | First algorithm capable of auto‑generating melodic contours. | | 2022 | Melody Marks beta – manual annotation tools for creators. | Tested UI/UX and gathered community feedback. | | 2024 | Melody Marks 2.0 – real‑time collaborative tagging, multi‑instrument support, and adaptive visual styles. | The mature feature set you’re reading about now. |


  • Toggle Layers – hide the harmonic layer to concentrate on melody, or overlay both for a full analysis.
  • Export – download the mark set as MusicXML, JSON, or a PDF “melodic map” for offline study.

  • Mat6Tube (pronounced “mate‑six‑tube”) is a web‑based platform that hosts user‑uploaded music videos and audio tracks while allowing contributors to attach Melody Marks to specific moments in the media. Its core features include: Tip – Use the “Batch Apply” button to

    Mat6Tube’s name reflects its dual focus: Mat (short for “musical analysis tools”) and 6Tube (a nod to the familiar “YouTube” brand, indicating a video‑centric experience).


    | Feature | Description | Benefits | |---------|-------------|----------| | Collaborative Marking | Multiple users can simultaneously edit marks on a shared video (real‑time conflict resolution). | Enables classroom live‑annotation and community‑curated analyses. | | Multi‑instrument Support | Marks can be linked to a track map (e.g., piano, bass, synth). Each instrument gets its own layer. | Facilitates full‑arrangement breakdowns. | | Adaptive Styling | Marks automatically switch colour palettes based on the viewer’s UI theme or color‑blind settings (e.g., deuteranopia‑safe palette). | Inclusive design. | | Machine‑Learning Suggestion Modes | Three levels – Basic (simple contour), Pro (motif classification), Expert (harmonic‑function inference). | Gives creators control over AI assistance. | | Export to Notation | Direct conversion of marks + pitch data to MusicXML and LilyPond files, preserving articulations and dynamics. | Bridges the gap between video and printable scores. | | Audio‑Reactive Visuals | In “Performance Mode”, marks animate in sync with the live audio (e.g., a pulsating halo around anchors). | Enhances live‑stream engagement. | Mat6Tube is a next‑generation


    Mat6Tube is a next‑generation, AI‑enhanced video‑hosting platform that specializes in music‑centric content: tutorials, performances, production breakdowns, and algorithmic composition showcases. One of its signature features is Melody Marks—a set of interactive visual annotations that overlay a waveform or piano‑roll view, highlighting melodic structure, phrasing, and expressive intent.

    Melody Marks turn a raw audio track into a readable musical map, making it easier for:

    In short, Melody Marks are the semantic layer that sits between raw sound and musical understanding.
