Count of Beats: How to determine the frequency of Unknown Tuning Fork

7 Comments / Blog /

Count of Beats : How to determine the frequency of Unknown Tuning Fork Beats is a popular word among musician. Using beats formation concept, they tune their instruments while playing them against some standard frequency. All instruments come into tune when beats disappear. Now the instruments sound with same standard frequency which implies that there has […]
