Mood Keys

Tell it how you feel, it plays music that matches

Fun

The Problem

Finding the right music for your mood requires searching; existing music has endings

Current Solutions (Not Great)

Spotify playlists (end, require choosing), lo-fi streams (no personalization), meditation apps (subscription)

Who Needs This

Focus workers, meditators, streamers needing background, relaxation seekers

Sometimes you don't want to play—you want to be played for. Mood Keys generates ambient music based on your emotional state or desired atmosphere. Say 'calm', 'energetic', 'melancholy', 'focused', or describe what you want, and it creates an evolving soundscape. Not a playlist of existing songs—truly generated music that matches your mood, plays indefinitely without repeating, and can shift with you. Use it for focus, relaxation, meditation, or just filling space with emotionally appropriate sound.

Honest Take

The ambient/generative music space is absolutely saturated with lo-fi streams, Brain.fm, Endel, and countless YouTube channels. You're competing with free alternatives and established subscription services. The local/private angle is interesting but probably not enough to overcome the crowded market.

Build a React PWA called 'Mood Keys' using WebInfer and Web Audio API. Mood input: text field or speech via Web Speech API. Mood interpretation with generateObject: { mood: string, musicalParameters: { tempo: number, key: string, mode: 'major'|'minor'|'modal', complexity: number, density: number, brightness: number, rhythmicActivity: number, harmonyType: string } }. Music generation: from parameters, generate note sequences. Use generateObject iteratively: { nextNotes: [{ pitch, duration, velocity, instrument }], nextChord: string, evolutionDirection: string }. Web Audio synthesis: multiple layers (pad, bass, melody, texture) using oscillators or simple samples. Evolution: parameters drift slowly, music never loops exactly. Mood transition: when new mood input, smoothly interpolate parameters over 30 seconds. UI: ambient visualization (particles, colors matching mood), mood input field, timer setting, current mood display. Save moment: capture current state as MIDI or audio clip. Genre flavors: ambient electronic, piano only, orchestral, nature sounds. Timer: set duration, gentle fade-out. No tracking of moods—completely local.
