Explore three-notes-per-string scales and guitar modes
This interactive 3NPS fretboard map shows how seven three-notes-per-string scale positions connect. Select a tonic, scale family and mode to explore the major scale modes, melodic minor modes and harmonic minor modes using note names, intervals or uncluttered pattern shapes.
What you can learn
- See all seven connected 3NPS positions for each supported scale family.
- Understand a mode from its own tonic rather than as an isolated box.
- Learn the interval formula and characteristic notes of each guitar mode.
- Compare note-name, interval and shape views across the fretboard.
How to use this tool
- Choose the tonic note and the major, melodic minor or harmonic minor family.
- Select a mode, then move between its seven connected positions.
- Use interval view to identify the tonic and characteristic colour tones.
- Practise one position slowly, then connect it to the position on either side.
Frequently asked questions
What does 3NPS mean on guitar?
3NPS means three notes per string. These scale fingerings place three notes on each used string, creating consistent patterns that suit alternate picking, legato and connected fretboard movement.
How many three-notes-per-string positions are there?
A seven-note scale has seven connected 3NPS positions. Each position begins from a different scale degree while containing notes from the same parent scale.
Are guitar modes separate scales?
Modes can be understood as different interval relationships created when a scale is heard from a different tonal centre. The explorer shows both the connected parent-scale positions and each mode’s own tonic and interval character.
