The goal of the Portatone is to make it easy for everyone to appreciate the joy of performing music. The PSR-E series includes both lesson functions and a variety of timbres that make them ideal for both the beginning player and the street musician. Entry-level models have typically had bright color schemes and rounded designs to appeal to young players. The PSR-E series models, on the other hand, have a sleek design intended to appeal to both the beginning player and the street musician. The PSR-E343/E243 are designed to be visually appealing to people of all ages and backgrounds, with a solid synthesizer-style design. The PSR-E343/E243 convey a taut sense of solidity through flat surfaces and sharp edges that reveal different aspects of their character from different perspectives—gravity and seriousness to the player, lightness and intimacy to the audience. Two types of hairline patterns create visual variety on the top deck of the PSR-E243 and organize the interface around a strong centerline, so that players can quickly identify functions when playing, and familiarize themselves with the performance space in this entry-level model.
