Frequently asked questions
Will an online piano replace a real instrument?
No – online piano is good for: experimenting, basic theory, having fun, practicing melody. What's missing is: "touch response" (pressure dynamics), pedal (sustain), physical learning of the keyboard layout, and satisfaction with a real instrument. For serious learning: buy a MIDI keyboard (88 keys, weighted keys) from PLN 300-600.
How to quickly learn to play a simple melody?
Choose a simple melody: "Ode to Joy", "Happy Birthday", the C major scale. Identify musical notes: use the musical notes tutorial. Practice slowly: one note at a time. Memorize the sequence without looking at the notes. Gradually speed up. Use finger marks. Simple melody = 30-60 minutes of exercise.
What is the best way to learn piano online?
Structured apps: Simply Piano (gamification, great for kids), Flowkey (thousands of songs), Playground Sessions (with Quincy Jones). YouTube: Piano Tutorial Show, Rousseau (visualizations). Theory: musictheory.net. Online tutor: Preply, AmazingTalker. Tutorial: "Alfred's Adult All-in-One Piano Course" for adults.
What is MIDI and how does it work with online piano?
MIDI (Musical Instrument Digital Interface): a standard for instrument communication. The MIDI keyboard sends signals (note on/off, velocity) to the computer. Web MIDI API (Chrome): The browser can receive MIDI. Piano Tool supports Web MIDI if you have a MIDI keyboard connected via USB. Programs: GarageBand (Mac), LMMS (free) for MIDI recording.
How to recognize notes on a staff?
Treble clef (clef, left hand, right hand higher): EGBDF (Every Good Boy Does Fine) lines, FACE spaces. Bass clef: GBDFA (Good Boys Do Fine Always) lines, ACEG (All Cows Eat Grass) spaces. Middle C: between both staves (small auxiliary line). Note: head + tail + beams (for short values).
