5 charts, 140-240 BPM. Each one is read from a real score: play it along to the record, slow it down, or take the practice course under it.
5 Diseased Ways drum parts are transcribed here, 771 bars of music in total, filed under death metal, instrumental and rock. Every one of them is a chart read from a real score rather than a tab somebody typed out: the notes are where the score put them, the tempo is the record’s own, and the page plays the recording underneath while you read.
Nothing here asks you to play it at full speed on the first pass. Take any chart down to half tempo, loop the four bars that will not come clean, and bring it back up. 5 of these 5 songs also have a practice course under them: the part broken into the few things actually different about it, one at a time, ending with you playing the whole song against the record.
A good place to start is "Song 3" at 140 BPM, the slowest of them, or "Song 4" at 125 bars, the shortest. Sheet music, tab, MIDI and MusicXML download from every chart if you would rather read it away from the screen.
