Support for Chord Chart Writing for Your Favorite Songs

Product Features

• This application analyzes audio recordings to assist with the creation of chord charts.
• Using proprietary Casio Chordana technology, audio files stored on your iPad or iPhone are processed to display detected chords visually, along with real-time instrument finger positions during playback.
• The app allows playback of the analyzed chords on a virtual instrument pad, enabling verification and manual editing for improved accuracy—facilitating more efficient chord transcription compared to listening alone.
• Analyzed and edited chords can be saved, emailed to other Chordana Viewer users, or printed with AirPrint-compatible printers.
• Please note that while the chords provided aim to match the song's mood, they may not correspond exactly to the original recording's chord structure.

Chord Display and Real-Time Guidance

• The app features a chord display pane that shows analyzed chords, complemented by a moving guide bar synchronized with playback for real-time chord monitoring.
• Full-screen mode enhances visibility for focused practice.

Chord Guide and Editing Functions

• Tapping on a chord in the display reveals specific finger positions for the selected instrument in the Performance pane.
• Chords can be manually edited by choosing from up to three closest-sounding candidates or entering custom chords; barline positioning can also be adjusted.

Performance Mode and Instrument Interaction

• The performance pane allows users to navigate through chord positions by simulating piano or guitar finger placements, matching displayed chords.
• A chord list provides additional reference for chords not shown directly in the display.
• Piano or guitar pads enable playback of chords; individual notes can be played via a virtual keyboard. The recording function supports capturing performances for review or sharing.
• Additional instrument sounds and tones are available as optional add-ons for enhanced practice options.

Tempo, Key, and Vocal Tone Adjustment

• The app allows users to import audio files stored on their device for real-time modifications such as changing tempo, transposing key, and balancing vocal versus accompaniment levels—facilitating transcription and practice.
• Transposing the key automatically updates chord displays for consistency and ease of use.

The Technology Behind Chordana

• The Chordana series leverages advanced Casio proprietary technology capable of extracting natural-sounding chords from complex audio waveforms by analyzing timing, frequency distribution, harmonic content, melodies, and rhythm instruments within recordings—delivering highly accurate musical transcriptions with unprecedented fidelity.
