Explorador Musical: music theory across the fretboard
A free Portuguese-language music-theory toolkit for learning, practicing, tuning, and exploring chords and scales on guitar, bass, and keyboard.
- For
- Portuguese-speaking guitar, bass, and keyboard learners
- Worth noticing
- Its topic index links chord shapes to compatible scales, and interval pages to sound, inversions, fretboard positions, chords, and scales.
Field notes
The homepage divides its references into task-oriented sections rather than presenting one long theory lesson. It describes chord libraries with inversions and compatible scales, arpeggio diagrams using five CAGED shapes, and a concept map linking related topics. Practice material is described as including tablature, a metronome, repetition, and timed routines. These are homepage descriptions; the extracted evidence does not establish that each interaction was tested.
