Why a Laptop Is Perfect for Harmonium

A laptop gives you the ideal setup for playing harmonium online:

  • Built-in speakers — hear your playing immediately, or plug in headphones for private practice
  • Portable — practice harmonium anywhere you take your laptop
  • Large screen — see the full keyboard layout and control panel without scrolling
