FARMINGDALE, N.Y. /Music Industry Newswire/ — ­Planet Waves, one of the D’Addario Company’s family of world-renowned musical instrument accessory brands, introduces Scale Wizard, a comprehensive guitar scale library as a companion to their best-selling Chordmaster App, a quintessential guitar chord library. Between them, Scale Wizard and Chordmaster provide volumes of guitar reference material in a hand-held iPhone and iTouch App.

Offering over 10,000 scale, mode, and arpeggio shapes, a left-handed view and alternate tunings, Scale Wizard is the most complete scale application on any platform. With an interface truly optimized for iPhone and iPod touch, guitarists can swipe a finger up and down the fret board to hear ascending and descending scales or tap the screen to hear individual notes played by a skilled professional guitarist. Multiple positions of each scale, mode and arpeggio along with adjustable playback speed make Scale Wizard the perfect learning, reference, and practice tool for any level of guitar player.

Having reached the #1 selling App in the Music Category on the Apple App Store, Chordmaster offers a comprehensive and accurate library of over 7,800 guitar chords, displaying notes and fingerings on a virtual fret board. While allowing users to view each chord in every position up and down the guitar neck, players can even strum the virtual strings to play and hear each chord in pristine audio. The library, separated into root, chord type and chord variants, allows users to navigate to any chord easily and quickly and even comes complete with a “lefty mode” for the often-ignored left-hand guitarist.
