Picture yourself sitting down with a friend to perform a song together. However, when you attempt to play the same notes at the same time, the result is unpleasant, with sounds of clashing and dissonance. Playing out of tune can cause unnecessary tension and unpleasant harmonies. Instead, we can create beautiful resonances by focusing on our sounds' intonation, balance, and blending. 

This website aims to help you develop your musical skills, understand the pitch tendencies of your instrument, and encourage you to engage in different types of listening while performing in an ensemble. This website will teach you which notes naturally play sharp or flat on your instrument and how to adjust your playing to remedy intonation issues.

Musical intervals are measured in cents to determine the distance between them. When using equal tempered tuning, an octave is divided into twelve semitones of one hundred cents each. Tuning an instrument involves preparing it to play the intended pitch without being too high or too low. The distance of how high or low is measured in cents.

During the process of tuning an instrument, the tuner will show three possible readings: flat (too low), in tune, or sharp (too high). A needle (electronic line) on most tuners will show where the pitch falls. The needle will shift to the left for flat pitches, to the right for sharp pitches, and stand straight up for the correct pitch. However, sharp and flat pitches illuminate different circle parts on the Tonal Energy app (as shown below).
