WhySummon Aery

Summon Aery is a great option for Sona both offensively (with autos and [Q]) and defensively (with [W]).

WhyManaflow Band

Manaflow Band is a great option here for Sona because you're going to want to play aggressively in lane early spamming [Q].

WhyCelerity

Celerity's bonus Movement Speed is great to for helping you to position better in teamfights so that you aren't quickly dying from your low health pool.

WhyScorch

Scorch allows you to dominate the lane phase if you're able to consistently poke with your [Q].

WhyBone Plating

Bone Plating on Sona provides fantastic early-game mitigation so that you're able to take good trades with [Q] poke and an empowered Auto Attack.

WhyRevitalize

Revitalize synergizes extremely well with Sona's [W] especially heading into the mid to late game when you've built a few extra heal/shield items.
