iPad User Guide

Callus Logic for iPad is the guitar simulator app that allows you to:

• Play any note or chord on the guitar's fretboard.
• Easily load chords, scales, and arpeggios in any key.
• View one list of all basic "beginner" chords and see common fingerings.
• Instantly view common fingerings for any chord.
• Instantly view the interval above the root for any chord or scale.
• Instantly see what fret number any note is found on.
• Instantly use one of two different number systems to more easily analyze and understand the music theory behind specific chords and scales.
• Create collections of fretboards to save all the scales and chords used in a particular song or exercise.
• Play a song in any Music app, then open Callus Logic Mobile and play along to that song. This is great for figuring out what key a song is in.

To Get Started:

1. Select Scales, Chords, or Basic Chords from the segmented controller.




2. Use the Root and Accidental scrollers to select a root note for the chord or scale.
   For example: For E, select the note "E" and the accidental "Natural".
   **Note: if loading a Basic Chord, the root and accidental scrollers are unavailable, continue to the next step.





3. Tap on the Scale/Chord selection button to reveal a popover menu of available scales or chords.
   **Note: Arpeggios are selectable from the Scales popover menu (towards the bottom).
   **Note: for basic chords, the root note is listed in the Scale/Chord selection button and popover menu.





4. To switch between note labels, tap on the Display Mode Scroller, and select:
   • Notes
   • Fret Numbers
   • Intervals
   • Chord Fingers
   • Numbers 0-11
   • Numbers 0-39
   
   

   **Please Note:

   • "Chord Fingers" is only available when either Chords or Basic Chords are selected.
     
     • I = Index finger
     • M = Middle finger
     • R = Ring finger
     • P = Pinky finger
     • O = Play the open string
   
   
   • "Numbers 0-11" replaces note names with numbers:
     • E = 0
     • F = 1
     • F# = 2
     • G = 3
     .
     .
     .
     
     • D# = 11
   
   
   • "Numbers 0-39" assigns a number to each distinct pitch on the guitar:
     
     • The lowest pitched "E" note is 0 (in standard tuning).
     • The E one octave up is 12. For example on the 12th fret of the low E string.
     • The E two octaves up is 24. For example on the open high E string.
     • In standard tuning, the highest pitch on a 15 fret guitar is 39.
     • This number system allows you to quickly find Notes that are the same pitch on different strings.
     • It also makes it easy to calculate the distance (in half steps) between 2 notes on the guitar.
