Any format/encoding may be used, so long as a codec existed prior to the creation of this challenge
Any instrument (a real instrument, MIDI synthesis, etc.) may be used
The tempo must be 65 BPM (as notated in the sheet music) - if you cannot get exactly 65 BPM, you may use any tempo within the (inclusive) range 64.75 - 65.25
The sheet music is in concert pitch
Equal temperament tuning must be used (specifically 12-ET with A4 = 440 Hz)

For reference, here is a Stack Snippet that will play the excerpt:

Explanation
LetterNumber@&quot;uursuursuikmnprsrrnprrfgikigifgiggkiggfdfdbdfgikggkikkmnikmnprsu&quot;

Find the letter numbers of each character in the string (&quot;a&quot; -&gt; 1, &quot;b&quot; -&gt; 2, and so on), wrapped with a List. (This string represents Pachelbel's Canon in D)
#~(s=##~SoundNote~41&amp;)~1&amp;/@...

Set s to SoundNote function whose instrument is #41. Set the duration to 1 and map that function to each element in the List (thus making SoundNote primitive objects).
{14,18,21}~s~16

Make the last triad. (The duration 16 is there to make the last note 16 times longer--a whole note is sixteen times a sixteenth note.)
... ~Sound~18.5

Make a Sound object, 18.5 seconds long (because the tempo is 65 bpm [5 measures of 4/4 with tempo 65 bpm = approximately 18.5 seconds]).
126 byte version, non-competing
Sound[{(s=SoundNote)/@LetterNumber@&quot;uursuursuikmnprsrrnprrfgikigifgiggkiggfdfdbdfgikggkikkmnikmnprsu&quot;,{14,18,21}~s~16},240/13]

Non-competing because the output contains two sixteenth notes instead of an eighth note, and the separation is quite noticeable.
