This Tune icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,500 icons, all in the same style and quality.
This logo is three horizontal lines spaced evenly from each other. On each of the lines is a small rounded rectangle, taller than it is wide. The top and bottom rectangles are a third of the way from the left, and the middle rectangle is spaced a third of the way from the right.
