<p>A few reasons why Piano and Voice can work together:</p>
<p>1) Piano will require a standard amount of practice, but voice requires the least. That is because you can only sing for so long each day. I suspect that brass players are similar to voice (can only buzz the lips so long).</p>
<p>2) The same ensemble group can cover both Voice and Piano. There is no Piano choir, so piano majors typically take Choir to fulfill their ensemble requirement.</p>
<p>That leaves private lessons, and all the regular music classes.</p>
<p>However, given your goal, I would recommend majoring in voice, and just taking piano lessons. At most schools, there is a keyboard requirement for all music students. Note: Sight reading to the accompaniment level is a talent, and not necessarily a skill that can be learned.</p>
