GTK - Guitar Player's Toolkit

Tools for your guitar journey

Features & Capabilities

During the many phases of my guitar playing journey, I needed or used a number of tools. These included books on theory, tuners, metronomes, practice techniques, and information to help me get my head around some of the concepts like chord composition, triads, scales, modes, transpositions, or working out what a chord looks like on a fretboard. Despite being a much better guitarist than I was, I built these tools because I still use them. Now you get to use them too.

The Guitar Player's Toolkit includes the following tools:

Chord Theory

  1. Chord Master • A comprehensive chord library containing around 3600 chord voicings as well as the ability to create your own custom chords • Know where to put the fingers, but don't know what the chord is called? This gives it a name • Want to work out how to play a specific chord when you only have the note names? Shows all positions for these notes across the fretboard showing you where chords might sit and what to play • A triad library shows you finger positions across different string sets, inversions, and starting frets • A key based diatonic progressions library helps you with song writing and melody construction • All chords can be played with guitar accurate sounds to suit Nylon, Classical, and Steel strings.

  2. Scales Show notes across every key - major, minor, diminished, augmented, but also modes, pentatonics, blues, jazz, Arabic / middle eastern, exotic, symmetrical, Chinese, Japanese, Korean, and so on.

  3. Position Finder Want to play in a specific key, but at a place in the fretboard that suits you? Want to play without having to slide your hand up and down the fretboard? This tool show you the notes in the scale, and where they are on the fretboard in the place you want to play them in.

  4. Chord Transposer You often find a song that includes chords that you either don't like, or are too low or high for your voice. This tool lets you transpose all chords into a different key, or just recalculate your chords based on a capo position.

  5. Circle of Fifths An invaluable tool for song writing. This tool shows the relationship between keys and chords and also allows you to work with modes.

  6. Mode converter Allows you to convert from one musical mode to another, in any key.

Practice tools:

  1. Note Practice Want to learn where every note is on the fretboard? This tool gives you a way • Set a tempo/pace to practice at. Choose the strings, notes, and enharmonic format, and you'll be given a note and a string number to play. • You hear the note so you can compare it to what you hear on your guitar. See the note on the fretboard to help you learn. • Start with a single string, and then work across string pairs or collections until it becomes second nature.

  2. Triad Practice • Triads are combinations of 3 notes that make up chords. Learning these across string sets, and extend your mastery of the fretboard, chords options. • Similar to Note Practice - pick your chords, string set, type of chord (Maj/Min/Aug/Dim), an inversion (Root/1st/2nd), and a tempo to practice at.
    • You hear the chord/triad so you can compare it to what you hear on your guitar. See the triad on the fretboard to help you learn. • Start with a single string set, Maj/Min and increase the complexity in terms of diminished/augmented, and multiple string sets

Practical

  1. Tuner A chromatic tuner to identify what note is being played. Use this to tune your guitar to whatever tuning scheme suits you

  2. Metronome Provide a regular beat per minute and peats per measure (e.g 3/4, 4/4). You can also manually tap a Tempo to match a beat in your head.

Would love to see harmonic and other keys added to the position finder.
