&amp;#039;&amp;#039;&amp;#039;28/1&amp;#039;&amp;#039;&amp;#039;, the &amp;#039;&amp;#039;&amp;#039;28th harmonic&amp;#039;&amp;#039;&amp;#039;, is the [[harmonic]] past [[27/1]] and before [[29/1]]. It is about four [[2/1|octaves]] and ten [[semitone (interval size measure)|semitones]] in size. Used in harmony, it sounds particularly wide: if the lower note is F1, the higher note will be about Eb6. That is for all practical purposes beyond the range of {{w|choral music}}. However, it remains useful in some instrumental solos and ensembles. Like [[20/1]], it can be approached in various ways of stacking, such as 1–2–4–7–14–28. &lt;br /&gt;
