111 is the negative space between most of the Solfeggio frequencies. This weighed tuning fork is a great all round tuning fork. It is great for the relief of stress and it also helps with insomnia, it lift the mood, calms the mind and acts as a general balance. It encourages cell rejuvenation and release of Beta endorphins (these assist with pain relief) so also a good first aid tuner. A lovely fork to have alongside the unweighted Solfeggio forks.
The tuning fork is engraved with 111 Hz and comes with a blue pouch and a mallet to activate the fork.
