Arts Supplement question

<p>I have a question related to the arts supplement on the Common App. The letters of recommendations most schools request ask for those from teachers in major subject areas.
Yet the arts supplement states the following:</p>

<p>"Have an instructor who is familiar with your work send a letter of recommendation directly to the admission office, not to The Common Application offices." </p>

<p>So, does this mean it is OK to send another supplementary LOR from an arts related teacher, even to those schools that claim they do not want additional LORs?</p>
