In the beginning of the game you want to wait at your inner turret until your first to chimes will spawn. (This will happen at 0:25). As soon as your first to chimes have spawn you want to get them as quick as possible and then immediatly run back to your inner turret, The Third Chime will spawn at 1:25 collect this one as well and walk towards the enemy red/blue you want to ward this between 1:40/1:50 now watch if where the enemy jungler start you can see this to watch if the enemy botlane or toplane is later in lane.
When the jungler is almost done with the buff and is at his weakest point then it is your moment to stun the jungler against the buff or wall and with the high attacks speed from your runes and the empowered plus ignite you should be able to easy kill the jungler.
If it is a very tanky jungler just steal the camp and return back to lane

In the Laning phase with Bard you should keep in mind that the jungler is behind and should not be able to gank early. Now you are able to play very aggresive but still leave some shrines under your turret for back up HP for ecery chime you pick you should place one shrine under the turret. If you understand the Bard Q good enough try and stun through the minions! This is hard to dodge and predict.

In my opinion Bard has the best roam in the game so when your adc goes for a recall and you still have health and mana i like to go for a roam and recall next time. Make sure your roams are effective if you just walk around it is only lost time and XP. While roaming you have a phew goals.

1- Warding
Make sure you ward the river and maybe a bush in midlanem, this is will help your team to track down the enemy jungle to maybe get a kill or deny a gank.

2-ganking
Bard can make specials ganks with his Magical Journey if u make a good journey you and jungler can get behind the laner(s) and get a easy kill and push.

3- collecting
When you are roaming it is also so smart to get some chimes! This is will make your basic attacks stronger and give you XP.
