<h3>The tune and the many ways to change it</h3><p>A <strong>melody</strong> is a sequence of single notes, played one after another, that the ear follows as a recognisable tune. It is the part of a song you naturally hum. A good melody has shape — it rises and falls — and a clear rhythm.</p><p>Composers keep music interesting through <strong>variation</strong>: changing a melody in small ways while keeping it recognisable. There are three main kinds. A <strong>rhythmic variation</strong> changes the <strong>timing</strong> — making some notes faster or slower, or adding rests. A <strong>melodic variation</strong> changes the <strong>tune</strong> itself by adding extra notes or reordering them to give a fresh perspective. A <strong>dynamic variation</strong> changes the <strong>loudness</strong>, using accents on certain notes or moving between soft and loud passages to create emotion and contrast.</p><p>Used well, variation lets one simple tune carry a whole piece of music without becoming boring, because each repetition arrives with a new twist.</p><div class="callout"><strong>Kenyan context:</strong> Listen to how a Kenyan choir repeats a chorus. The first time it may be soft (a dynamic variation), the next time the sopranos add a quicker rhythm (a rhythmic variation), and finally a harmony line adds new notes (a melodic variation). The same tune feels fresh each time.</div>
