b stands for black. 8b is blacker (softer) than 6b.
Each graphite pencil, the 6H, 6B, 2H and 2B, will create a sharp line and fine detail. The difference is that the softer leads (2B, for example) will need to be sharpened more often to keep drawing this detailed. That is because, while having a sharp point when freshly sharpened, the softer the lead, the more quickly it will wear/crumble down.
Drawing pencils are classified by the hardness or softness. The harder the pencil, the lighter the led's gonna be. The softer, the darker. I believe the names for the pencils from harder to softer are: 6H, 4H, 2H, H, HB, B, 2B, 3B, 4B, 5B, 6B, 8B. And there might be some new ones called F and XX9. I think. Anyway, the H's are the harder, you can remember that because H could stand for "harder." The B's are the softer. And if you remember the H, then you won't need to remember the B.
Pencils with H are harder, pencils with B are softer. The higher the number with the H, the harder the lead (usually light, very precise line). Pencils with B are softer, and the higher the number, the softer the lead (very dark, blurs easily).
If you want. Pencils with higher numbers such as 6Bs give a darker stroke and are softer. So, if you don't mind using a harder, slightly lighter pencil, then go ahead.
For the walls use a 8B but for the doors and outlining of the appliances use a 4B and windows use a 5H.
6b+b+b is the same as 6b+1b+1b you can add the numbers together if the variables are the same. 6b+1b+1b=8b
It is 17b when simplified
In order, the leads are (from softest to hardest): 9B/8B/7B/6B/5B/4B/3B/2B/B/HB/F/H/2H/3H/4H/5H/6H/7H/8H/9H HB is the most commonly used lead for general purposes. The softer leads are used for art drawing, the harder for fine ledger work.
6B is the darkest.
6B, 7B, 8B, 9B, 10B, 11B, 12B, 13B, 14B, 15B, 16B, 17B, 18B, 19B
6B, 7B, 8B, 9B, 10B, 11B, 12B, 13B, 14B, 15B, 16B, 17B, 18B, 19B
B is the atomic symbol. a number of different Isotopes exist for this element.6B, 7B, 8B, and so on and so forth.
6c you nerds out there and the next one is 6b,6a,7c,7b,7a,8c,8b,8a and so on

Honestly, it's very easy. First of all, DO NOT start out on 4B. It only hinders your growth. Start off on 5B and play with a 2X or 2.5X speed multiplier. Once you can beat brainstorm on 5B play 6B. Start off on level 7 songs, then once you cam beat brainstorm on 6B, continue to play until you unlock 8B mode, if you can beat level 9 songs on 8B you are now a "PRO"! enjoy!
lead, copper is a metal therefore it is harder
