This one is not transposed. Unlike the other two pages in this library, Mojito is already in A minor and needs only two black keys, so it is written here exactly as scored. Every drill shows both hands on one grid, with the count on every attack.

Read the counts down the column: 1 is the downbeat of a bar, 2 3 4 are the other beats, and e & a are the sixteenths in between. Any two cells sharing a column are struck at the same instant.

Law one

Two black keys, and one of them matters

Of 1,121 notes, only 52 are black. Thirty-one are G♯ and fourteen are C♯. The G♯ is the leading tone in every E chord — it is what makes the progression pull home. Learn those two keys and the piece is otherwise white.

Law two

Four chords, over and over

The bass walks the same short cycle for most of the song: A · D · C · E, sometimes ending on B instead of E. Once your ear catches the cycle you can predict where nearly every bar is going, and the left hand stops being something you read.

Law three

Only 69 bars are new

Twenty of the 89 bars are note-for-note repeats of a bar you have already played, and the second chorus is nine-twelfths identical to the first. Learn the chorus properly and a quarter of the song comes free.

Running order

all 43 bars, your sequence

Hear the whole thing before you learn any of it. The drills further down teach the sections in printed order; what you play is a separate decision. Move the blocks below and the whole piece plays back in that sequence — every bar kept, nothing dropped, just resequenced. Sections A–D are the Journey to the West theme; E and F are where the arrangement leaves it.

Time0:00 / 0:00

Playback follows the tempo at the top of the page. Switch between as printed and with rolls to hear the difference the spread chords make: bar 8 becomes a single roll instead of seven hits, the four held bass chords in bars 17–20 spread bottom to top, and the last chord of the piece opens out slowly. Everything else is identical, so the comparison is clean. Both settings play the voices no pair of hands can reach in bars 5–7 and 39–40 — a synthesiser has no hands.

Honesty

What this page does and does not do

read before you start

Built from the MuseScore file in your repository. The notes and rhythms are exactly as scored — nothing transposed, nothing simplified. Three things are worth knowing.

Original key
The other two pages in this library flatten every black key. This one does not. Doing it would mean turning G♯ into G, which changes every E major chord into E minor and removes the pull the whole progression is built on. In a song like this that is not a simplification, it is a different song. The two black keys are worth learning.
Bar 44
The one awkward bar: a chromatic fill using all five black keys — A♯, C♯, D♯, F♯ and G♯ — with sixteen left-hand attacks. It is the only bar in the piece like this. Give it its own practice slot and do not let it hold up the rest.
The fingerings
Derived from each passage’s hand position rather than checked bar by bar. Where a hand stays inside five notes they are reliable. Where the hand shifts, the drill says so and the numbers are a starting point — trust your own hand over them.
Practice

Where to start

89 bars, 69 of them new

Do not start at bar 1. Learn the chorus first, because most of it comes back later untouched, then fill in around it. The fill at bar 44 is the only thing here that needs real technical work.

Feel

This is a Latin groove, not a straight-eighths pop song. The left hand is the rhythm section: keep it light and absolutely in time, and quieter than you think it should be. If the bass gets heavy the whole thing turns into a march.

Pedal

Sparingly. Change on every bass note, which is roughly once a bar through the verses, and lift almost completely in the busier bars. Too much pedal is what makes this song sound muddy; the groove needs air between the notes.
