# nanananana Play the Batman theme song from your terminal without any external dependencies! ## Installation ```bash npx nanananana ``` No installation required! Just run the command above to play the Batman theme. ## Features - Plays the classic "Na na na na na na na na BATMAN!" theme - Uses a full range of notes including sharps/flats - Piano-like sound with proper Attack-Decay-Sustain-Release envelope - Implements gradual piano-like fading for notes that mimics real piano acoustics - Supports sequenced music patterns - Features alternating patterns that simulate multi-channel playback - Uses music theory principles to create clean, non-vibrating chord sounds - No external dependencies required to play sounds - Works on macOS, Windows, and Linux - Displays a cool Batman logo - Seamless note transitions with no audible gaps between notes ## Command Line Options - `npx nanananana` - Play the classic Batman theme - `npx nanananana --basic` - Play the basic piano-style version without extra features - `npx nanananana --piano` - Demonstrate piano-style playing with independent hands - `npx nanananana --help` - Show command line options ## How It Works This package uses Node.js built-in capabilities to play sound: - On Windows, it uses PowerShell's `[console]::beep()` - On macOS, it generates WAV files on the fly and plays them with `afplay` - On Linux, it attempts to use the terminal bell or `aplay` when available For chords and multi-note playback, it implements: - Proper harmonic synthesis that mimics the way piano strings resonate together - Piano-like envelope shaping with realistic attack, decay, sustain, and release phases - Independent left and right hand parts with different note durations - Gradual fading of notes that simulates real piano acoustics - Detailed overtone generation based on musical intervals For multi-part sequences, it uses carefully timed patterns with silences and alternating notes to create the impression of multiple tracks playing simultaneously, while maintaining pristine audio quality. ## License MIT
