It originates from a personal requirement for being able to put together a chart of notes to practice. This could be for a scale/mode or a chord across the instrument. Basically it helps you focus on the notes you wanna play and practice. For instance on a musical keyboard, you may want to just highlight the C Minor scale so that you can play over it. This little app will let you select the required root note and the scale to generate this:\n\n![johann-piano-scale.png](./johann-piano-scale.png)\n\nThe same can be done for a triad. You can generate a sheet with just the notes of the C Minor chord to practice it's notes across the fretboard (or in this case the musical keyboard):\n\n![johann-piano-chord.png](./johann-piano-chord.png)\n\nThe green dot is the root note and the blue dot is a note from the selected scale or chord.\n\nThe same can be done for guitars...\n\n![johann-guitar.png](./johann-guitar.png)\n\nand computer keyboards too!\n![johann-keyboard.png](./johann-keyboard.png)\n\nDemo: https://scribbletune.github.io/johann/#/\n\n### Develop\n\nRun `npm i`\nBegin dev with `npm run dev`\nLoad http://localhost:8081 in your browser\n\nBuild with `npm run build`\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fscribbletune%2Fjohann","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fscribbletune%2Fjohann","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fscribbletune%2Fjohann/lists"}
