It can be seen as the most consonant interval after the octave, which is the reason for its usage as an equave in systems such as [[Bohlen-Pierce]] tuning. Tritave-equivalent systems tend to avoid prime 2, only involving ratios between odd numbers (such as [[9/7]] and [[5/3]]). As such, timbres chosen for tritave-equivalent music tend to include mostly odd harmonics, such as the clarinet.&lt;/div&gt;</summary>
