  • You misunderstand what a learning curve means. The x-axis is the desired level of productivity/proficiency, and the y-axis is necessary knowledge/skill. A steep learning curve means you need a lot of knowledge/skill to even be slightly productive/proficient, making the learning process daunting for new users. A gentle learning curve means you get rewarded throughout the learning process with frequent productivity/proficiency gains. A “cliff” means there will be a long period of learning with little to show for it until the end.




  • Violinist here.

    Violins make sound by dragging the bow (stretched horse hair) over a string, causing the string to vibrate. At the micro level, the bow pulls the string to one side using friction, until the tension on the string pulls it back - this happens hundreds of times per second, and forms the basis of the sound we hear. Horse hair is slippery by default. To create the necessary tension violinists apply a small amount of solidified tree resin by wiping a piece along the length of the bow. This piece of hardened resin has the same approximate texture as glass or hard candy, and is called rosin.
