The routes we used for Tijeras > Music and Milwaukee > Pico > 13020 were the same as the ones laid out by previous trip reports, so I'll save you the hassle of reading a long-winded essay and just give you this: https://www.14ers.com/php14ers/tripreport.php?trip=19781.
The descent off Music's north ridge is best done on the left (west) side of the ridge proper. The ridge proper is blocky with spires and requires more descent/ascent/5th class downclimbing than you want to spend your time on. Staying to the left of the ridge is pretty simple, as you can easily hop on sturdy grass ledges to contour or downclimb stepped/slabbed gullies to descend. Make sure you don't descend lower than the true saddle of the Milwaukee-Music ridge. Once you get to the saddle, continue to stay left of the ridge proper to ascend Milwaukee. I will not sugar coat this: the Milwaukee ascent is a slog, and you miss out on the amazing scrambling on Milwaukee's NE-E face. Easily the least inspiring (route-wise) of the whole traverse, but it's by far the best way to connect these two amazing scrambles.
Descent off the north shoulder of the Music summit block (climbers are wearing blue).
Ledges to follow. I find great satisfaction in linking up some noice ledges.
You could follow the ridge proper if you'd like, but I would save time for the better scrambling later on.
THE SLOG (looking back on Music and Tijeras)
Once we hit the summit of Milwaukee, we used Dave Cooper's route description to finish out Pico and 13020. The only other word of advice I can give is that you should make the best effort possible to locate the trail over Milwaukee pass while you have a view of it from the Milwaukee-Pico ridge. We didn't find it until we were maybe 200' from the pass. It's not a huge deal-breaker, but if you can't find the trail, it's a lot of 3rd-4th class scrambling until you'll inevitably find it. All we know is that trail starts somewhere to the north of where my gpx heads up. The trail is actually pretty neat, and the whole time I couldn't help but think "who the heck would spend time to build this thing?".
I would say the best scrambling (in my opinion) was found on Music's south ridge, Pico's south face, and Tijeras NE gully/SE ridge, in that order.
TLDR: stay left for Music > Milwaukee
