There is not really a standard on the symbols used for writing drum sheets in the world, each continent have its own pitch that represents the different instruments of the drums. When I started to write drum sheets for the website I had to choose my symbols and I do not change any more so that all the sheets are uniform.
What I like in this writing is that the hihat, the snare drum and the bass drum are very clearly separated and it follows a logic of verticality with the bass drum at the bottom, the snare drum in the middle and the hi-hat at the top. For toms, I keep the logic high / low as on a piano.
Here are the symbols :
Main bass drum (BD)
Second bass drum (BD)
Snare drum or cross-stick (SN)
Closed Hihat (HH)
Opened hihat (HH)













On a “standard” drums, T2, T3 and T4 will be played.
