 Tempomapping is one of the most important parts of your chart; it is what makes it so the beat of the song syncs up to the audio. You should not chart anything until the tempo map is fully done, as you want your notes to follow the beat. Not only is this to make the charting itself much more sensible, but it also affects elements such as Overdrive, crowd clapping and the animation speed in-game, as they're all synced to it directly. Tempomapping is one of the most important parts of your chart; it is what makes it so the beat of the song syncs up to the audio.

There is already one at the start of the song with a Beats Per Minute (BPM) of 120 which can be changed, and you can add in additional ones to make sure the beat syncs with the audio throughout. +{{ :wiki_-_tempo_markers.jpg?400|}}This is done via Tempo markers in Reaper.

 Before starting, it is also recommended to understand the basic music theory of the beat of the song, and also understanding the basics of such things as downbeats, upbeats and syncopation. Before starting, it is also recommended to understand the basic music theory of the beat of the song, and also understanding the basics of such things as downbeats, upbeats and syncopation.

-While most songs are in a 4/4 time signature (4 beats per measure), some songs have different ones. Be sure to find out what time signature the song you're charting has to begin with, and change the very first tempo marker to that before continuing. You can do so by double-clicking on the tempo marker, checking the box that says "Set time signature", and adding in the correct time signature.+{{ :wiki_-_time_signatures.jpg?200|}}While most songs are in a 4/4 time signature (4 beats per measure), some songs have different ones.

 Once the audio is lined up at the start perfectly, its time to make sure it stays synced up throughout the song. First take a glance and see if everything seems to sync up perfectly as is, as sometimes a song has a static tempo throughout. This is common with electronic music, hip-hop beats, modern rock recorded to a metronome and other highly produced music. Once the audio is lined up at the start perfectly, its time to make sure it stays synced up throughout the song.

 First, look at where the beat starts desyncing from the audio. Then, add a new tempo marker on the previous beat and adjust the tempo of it to try and make things go back into sync. You can do this by having your cursor on the beat, then using the scroll wheel while hovering over the BPM button the toolbar below to change BPM for that marker only. First, look at where the beat starts desyncing from the audio.

-This process is often made much easier with the help of DIY Demucs stems; in most cases you wanna sync the beat to the drums, as they're the rhythm section that everyone else is following in the song. In some cases of very sloppy playing you might need to adjust the tempo marker to instead be what the full band intended to be at; using a metronome helps a lot in such cases.+This process is often made much easier with the help of DIY Demucs or studio stems; in most cases you wanna sync the beat to the drums, as they're the rhythm section that everyone else is following in the song.
