: interact with objects to toggle visuals and select sections on the music sheet
[1, 2, 3, 4]: select a finger and toggle their pressing state
[Z, X]: select the previous or next section on the music sheet
[W, S]: slide the selected finger to a different fret (also Up and Down arrows)
[A, D]: move the selected finger to a different string (also Left and Right arrows)
[R]: relax the fingers

To play the guitar strings:

  1. [P], [ / ] or Keypad 1
  2. [O], [ . ] or Keypad 2
  3. [ I ], [ , ] or Keypad 3
  4. [J], [M] or Keypad 4

If you press any of the parts of the music sheet with the mouse, or with Z and X, it will remember the state of your left-hand when you come back to it, so you can save hand positions in each of the 29 sections.

By pressing the ear, you will hear a recording of this piece performed by Ferran and mixed and mastered by Nomi.

About playing the guitar

The guitar consists of 6 strings, numbered in decreasing pitch. The first string [1] being the one with the highest pitch (an e or Mi). The lowest string [6] is tuned at the lowest pitch of this guitar which is also an E or Mi, 2 octaves below the 1st string.

Each string can be pressed at different places in the neck of the guitar called frets.
Pressing each fret, starting from the head of the guitar, will increase the pitch of that string by half a semitone per fret. In western music, 1 octave is divided in 12 semitones.

You play the guitar by pressing the frets on the neck of the guitar with your left-hand's fingers; and playing, strumming or plucking the strings with your right hand over the hole of the guitar.

How to read the sheet music

There are 2 types of written music in this digital piece.

  1. Original music sheet by Francisco Tárrega
  2. Section-long guitar tabs by Ferran

Reading the guitar sheet

To learn to read music sheets in general, we won't go into detail for now (!) please excuse us and come again later or find one of the many nice online resources about it such as this video!

In the music sheet, there are numbers that guide your fingers on the guitar.
In guitar, the left hand fingers are numbered as so:

  1. Index
  2. Middle
  3. Ring
  4. Pinky

A clean number in front of a note will tell you what finger you should press the fret with to play that note. Figure { I }

A circled number after a note will tell you what string to play that note. Figure { II }

A circled (0) will tell you to play that note on an open string (no fingers pressed on the string). Figure { III }

A C 2a on top of the staff will tell you to use a barre chord (cejilla) with your index finger on the indicated fret (in this case the 2nd). The index finger might need press all the 6 strings or as little as the higher 2 strings of the guitar. Figure { IV }

{ I } From left to right: Index (1), Ring (3) and Middle (2)
{ II } From left to right: Ring finger on the 3rd string, Middle finger on the 2nd string
{ III } On the right: Open string E played on the 1st string
{ IV } Barre (Cejilla) on 2nd fret with the Index finger. Note the finger number 1 on the first and the third note

You can zoom on the current section on the sheet, by clicking on the magnifying glass.
You can also display the music-staff visualization of the played note by clicking on the wine bottle.

Reading the guitar tablature

The guitar tab, visible by clicking on the onion, displays the 6 strings of the guitar, from bottom (low) to top (high).
Over each string-line, the number displayed tells us the fret number of the note that should be played.
Frets are counted from the head of the guitar. A number 0 represents an open string, or unpressed string.
The horizontal dimension of the tab represents time. Two numbers displayed on top of each other represent two strings that need to be played at the same time.
