Nose Flute - Extended range

prusaprinters

<p>This is a variation on Sebastian650's excellent nose flute design. I used meshmixer to make the mouth of the flute narrower, which allows much higher notes to be played.<br><br>Here's a table showing the range I can achieve with each model.</p><p>The “lowest note” indicates the lowest note playable.<br>The “highest clean note” indicates the highest note where a hiss from turbulence doesn't occur.<br>The “highest practical note” indicates the highest note that can be played at reasonable volume. It is possible to play much higher by simply playing much louder.</p><figure class="table"><table><thead><tr><th>Model \ Limit</th><th>Lowest note</th><th>Highest clean note</th><th>Highest practical note</th></tr></thead><tbody><tr><th>Original (4.8mm mouth)</th><td>F#4 (~370Hz)</td><td>G#5 (~831Hz)</td><td>G6 (~1568Hz)</td></tr><tr><th>3.3mm mouth</th><td>F#4 (~370Hz)</td><td>E6 (~1319Hz)</td><td>G7 (~3136Hz)</td></tr><tr><th>2.5mm mouth</th><td>F4 (~349Hz)</td><td>C7 (~2093Hz)</td><td>D8 (~4696Hz)</td></tr></tbody></table></figure><p><br>Playing tips:</p><p>Higher notes require much less airflow for the same volume. This makes it harder to be consistent on volume and tone. Also, for lower notes, a narrower mouth reduces the range of airflow at which a note is produced much. This makes the 2.5mm model a lot harder to play at first, but I've gotten used to it after a few days. An improvement on this design would be to constrict the air passage above the labium, so that breath control is easier.<br><br>To achieve the lowest note, make sure your lower lip rests as low as possible on the flute, even under it.</p>
