What it does
Most harmony tools are too theoretical or too simple. Coffee Piano combines a real piano studio, sampled Piano & Rhodes, MIDI, sustain pedal with a visual harmony engine. Orbit visuals show scales and chords as circular maps. A harmony map reveals voice leading and chord function. Reharmonize in one click per bar or full progression. Guitar diagrams sync to every chord. Works in the browser, no install, bilingual UI.
Web piano studio with MIDI, smart progressions, harmony map, and lifetime access.

- SHShow HN Pianoboi – displays sheet music as you play your piano2025 · pianoboi.site · ▲109
I made a software library for displaying piano music 7 years back, and recently ported it to the web (which is now easier than even ever). It displays sheet music as you play, and let's you take snapshots of specific chords, then keeps a running list of chords as keyboard visuals (instead of just displaying sheet music). Just a simple tool for songwriting/ figuring out songs by ear, or just understanding music key theory (which I'm admittedly a still a beginner at).
See chords as flags – Visual harmony of top composers on musescoreNov 2025 · rawl.rocks · ▲129I designed a relative piano-roll-based music notation. I used 12 colored arranged in a specific way to make visible the main effects and oppositions of Western tonal harmony. The tonic is always white, so a manual annotation/interpretation is required for each MIDI file. All chords are flags of three to four colors. Minor mode is darker, major mode is lighter. Colors are arranged in thirds. I sorted the pieces from simple complex harmony. I also wrote a bit of text to explain what you may see. There's also a corpus of structures: hyperlinks of tags that allow you to find similar…

Parallel agents, diff reviewer, and multi-model comparisons
Dev tools · May 2026 · kilo.ai
Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
