PopSongChordBook is a lightweight, 100% free, and ad-free interactive songbook designed to help piano, guitar, and ukulele players play along with their favorite pop songs in real-time.

Unlike traditional static chord sheets or heavily monetized platforms, PopSongChordBook uses a visual, auto-scrolling timeline system. This ensures you never get lost in a song, stop to turn pages, or lose your rhythm.

Key Features:

• Auto-Scrolling Chord Timelines: Play along in real-time with visual chord blocks that scroll dynamically as the song plays.

• 100% Free & Ad-Free: Enjoy an uninterrupted learning experience without paywalls, pop-up ads, or premium subscriptions.

• Multi-Instrument Diagrams: Instantly toggle chord overlays for Piano (with keyboard layouts), Guitar (fretboard fingerings), and Ukulele.

• Interactive Chord Trainers:

  • Piano Trainer: Connect any MIDI keyboard directly to your browser and practice chords with real-time feedback.

  • Guitar Trainer: Practice common chord progressions and verify your fingerings at your own pace.

• Transposition & Speed Controls: Easily transpose songs to fit your vocal range or slow down the playback speed to practice tricky sections.

• Clean & Lightweight: Optimized to load instantly on both mobile devices and desktops.

Why it is a great alternative to Ultimate Guitar, Chordify, or Yousician:

• Zero Paywalls: No locked features, no "pro" subscription prompts. Everything from transposing to instrument diagrams is completely free.

• No Ad Clutter: Free of intrusive banner ads or videos that disrupt your practice.

Visual Rhythm Alignment: Rather than just showing lyrics with chords printed above them, the scrolling timeline visually represents the rhythm and duration of each chord block, making play-alongs much easier for beginners.
