I recently finished this three part tutorial and figured it might bring you value, the tutorial explains notes and pitch, scale degrees and intervals, and in the last part how chords are created. Follow links below. 1. Notes explained (pitch, accidentals, semi-tone, the chromatic scale) 2. Scale Degrees and Intervals (scales, chord qualities) 3. Harmonizing Scales (musical key, the Nashville number system) Please reply or PM if any questions. Enjoy!
