I play bass and I always just listened to the song for 3 hours straight while figuring it out, writing down on makeshift sheet music the parts I got worked out. Could take hours or days depending on the song

Amazing folks can just run it through a program today, slow it down, I bet there is tech that can just, tell you the notes.

Amazing. I still learn manually this way lmao Sometimes I would just be fucking around and hit a spot, and suddenly realize thats part of a song I know, and it would all click into place.

Teaching my son to play guitar/read music this year and the tech today is so good. Hes years ahead of me when I was first starting out.

No tips, cuz I dont know the tech, I’m just impressed how far the tech has come in the last 25 years.

Dont play guitar, but on drums, i always just used VLC. it has both speed control and A-B loops.

and now gimme my bonus internet points!

Ardour and REAPER are free DAWs that you can use to both do that and record your performance

reaper.fm

When I’m doing that I use a program called Transcribe! It has every feature you could want for this purpose, really. You can mark off the individual sections, measures (and beats if you want) and take notes, looping them at any speed you want (with pitch correction), and it even has a tone generator you can use to check your transcription. It’s $39 dollars and well worth it. One time I sent the author an email and they promptly responded with great answers to all my questions.

I do try to do it the old fashioned way first, though. I’ll pull the song into Reaper or something and just play along.

If you are asking how to then search for this
