Ways to practise with it
- Root-note hunt: pick C, find it on every string, play each one and say "C".
- Octaves: pick a note and look for the two-strings-up, two-frets-up pattern.
- Songs: look up the root notes for easy bass songs.
Frequencies use standard tuning, A4 = 440 Hz. Check your tuning with the bass tuner.
