• Key “1” is the lowest note, ascending to the highest note key “23”
• Key “2” is often only found on the mavembe tuning
• Some mbira have extra keys (e.g. extra “17” on left side, or higher notes on the right beyond key “23” are most common)
• Note intervals can very, but all the octaves are divided into a

heptatonic scale, many being diatonic or at least nearly diatonic

• This diagram may not represent every mbira, but does represent the most common ones
