This ChucK program will play the loop heard in Jon Hopkins's song Light Through the Veins (hear it at https://www.youtube.com/results?search_query=light+through+the+veins+jon+hopkins )

//Notes in loop
392.00	=> float G4;
440 	=> float A4;
466.16	=> float Asharp4;
523.25	=> float C5;
587.33	=> float D5;
659.25 	=> float E5;
698.46 	=> float F5;


[E5, F5, A4, C5, Asharp4, G4, D5, A4, C5] @=> float notes[];

// run sine wave through envelope
SinOsc s => Envelope e => dac;

int counter;
0 => counter;

// infinite loop
while( true )
{
    // Note attack and fade
    50::ms => dur t => e.duration;
	notes[counter] => s.freq;

	// Play note and silence after the note
    e.keyOn();
    1000::ms => now;
    e.keyOff();
    40::ms => now;
    
    if (counter == notes.cap() - 1) {
    	0 => counter;
    } else {
    	counter++;
    }
}

Unfortunately when I wrote it out from what I heard in my head, I transposed it half a step up. In Hopkins's version, the high note isn't F5, it's E5. Whoops!
