Hi, I'm Sergei, the creator of Guitartonic. I've been playing guitar for 17 years, but never really learned how to improvise. Most of the elaborate music theory PDFs I found online overwhelmed me, so I built a simple tool to practice basic scales and modes. It worked so well that it even inspired my roommate to pick up his guitar again.<p>The app has been live for a few months. I had moved on to other projects and almost forgot Guitartonic existed, until the website started getting organic traffic.<p>I noticed that people were coming to the site (somehow, 90% of the traffic is direct) and staying for four to ten minutes on average. So someone was actually using it! I even received a few heartwarming messages from users saying Guitartonic rekindled their love for playing guitar.<p>Yesterday, someone donated $25 to support my work, which motivated me to share the project here and ask for feedback.<p>Fellow guitarists, how did you learn scales and improvisation? What helped you the most along the way?<p>I'd love it if you gave Guitartonic a try and let me know what you think!
