## Solo Description
Solo is the ultimate practice App for mastering fretboard visualization, designed by world renowned guitarists Tom Quayle and David Beebee.

Four powerful fretboard trainers allow you to work intuitively on each aspect of the visualization process; learning note names, memorising interval shapes, outlining chord changes, and practicing scales.

Solo asks you to find intervallic functions against one root note, chord symbol or scale at a time, listens to the notes you play, and doesn’t move on until you’ve correctly found each note by its intervallic function in the specified order.

Practice with Solo and finally learn your note names, master interval shapes, confidently play through chord changes and break out of scale boxes with intervallic functions. Start transforming your playing and confidence on the fretboard today!


NOTE TRAINER
The Note Trainer is perfect for beginner and intermediate players getting to grips with note names on the neck - the foundation of solid fretboard knowledge. 

‣ Solo shows you random root notes to find and listens, waiting for you to get it correct.
‣ Slide on the interactive fretboards for helpful diagrams and to study alternative options. Choose from 6 string guitar (standard and 4ths tuning), 7 string guitar, 4 string bass & 5 string bass.
‣ Optional practice suggestions offer challenging ways to limit and test yourself.
‣ Duration based workouts allow you to craft the perfect practice session.


INTERVAL TRAINER
The Interval Trainer will help players at all levels work on interval shapes with intervallic functions - the key to unlocking true freedom on the fretboard.

‣ Choose any combination of intervallic functions to practice.
‣ Create custom interval groups or choose the intervals for ANY chord type or scale.
‣ The Interval Trainer will randomise your chosen intervals and ask you to find them against either a fixed or random root note.
‣ Slide on the interactive fretboards for helpful diagrams, showing you where all of the interval shapes are across the neck, and to study alternative options. Choose from 6 string guitar (standard and 4ths tuning), 7 string guitar, 4 string bass & 5 string bass.
‣ Duration based workouts allow you to craft the perfect practice session.


CHANGES TRAINER
In the Changes Trainer you find intervallic functions, using single notes to outline different chord types or sets of chord changes, a key skill for learning to improvise through chord changes.  

‣ Practice outlining intervallic functions through over 100 common chord progressions and single chord exercises.
‣ 50 intervallic function levels. Go from simple chord tones to complex melodic structures and scales. 
‣ Solo intelligently maps out the correct intervals over each chord and listens for you to play each intervallic function in the specified order.
‣ Powerful workout options provide almost limitless ways to challenge yourself.
‣ Transpose the key of any progression or exercise. 
‣ Choose to randomly transpose the progression (or single chord exercise) each time it repeats.
‣ Work on voice leading chord tones through single note lines.


SCALE TRAINER
The Scale Trainer contains a vast array of scales and powerful workout options, allowing you to finally break out of the box and develop a much deeper understanding of how scales are constructed on the fretboard.

‣ Practice finding scales on the fretboard using intervallic functions. 
‣ Over 50+ Scales and modes.
‣ Powerful workout options provide almost limitless ways to challenge yourself.
‣ Melodic sequence options let you focus on starting from any chord tone within the scale.
‣ Duration based workouts allow you to craft the perfect practice session.

## Solo Reviews in Spain

### ***** "Genial"
Una App buenísima para aprender fácilmente los intervalos en el mastil.
-- Scaneitor, 2024-07-24

### ****- "Excellent tool but"
It s a very well designed app that  gives very good results in maping and knowing better your fretboard.

I just wish that when playing  the asking notes we could hear in the background the corresponding chords so we could establish a better connection with the note structure of the chord and the chord itself.  A metronome fonction would be nice too to keep the exercices fluid.

The customer service is very good. I wrote them and got a kind reply the very same day.
