Getting Fly Me To The Moon Under Your Fingers
The original version by Jimmy Van Heusen and Johnny Mercer is written in 4/4 time at around 120 beats per minute. Most fake books have it in the key of F major, but you will find it transposed everywhere depending on who is singing. The chord progression is straightforward—starts on Fmaj7, moves through Bm7b5 and E7, circles back through A7 and D7, then hits that Gm7-C7 turnaround. It sounds simple when you hear it. The piano arrangement adds more movement than you might expect on first listen. I usually pull arrangements from MuseScore or the Real Book. The fake book versions are clean and reliable but leave a lot to interpretation. Individual sheet music sites like Musicnotes and Sheet Music Plus have arranged versions at varying difficulty levels. For learning purposes, I stick with lead sheets from the Real Book and add my own voicings. That way I know exactly what I'm playing rather than decoding someone else's arrangement choices. Here is the thing nobody tells you about learning this tune: the left hand pattern is where most people stumble. The standard walking bass line follows the chord tones on beats one and three, but the bridge changes things up. You play a descending chromatic run from Ab down to G, which means your left hand has to be precise on quarter notes while your right hand is landing complex voicings. I spent about two weeks working just the left hand separately before it stopped fighting me. The practice method that actually worked was isolating the bridge first, playing it at half tempo with a metronome until my hands stopped crossing over each other awkwardly, then gradually bringing it back to speed. That cut my learning time significantly compared to just running through the whole thing repeatedly.
Voicing Choices That Actually Matter
Beginners tend to play root position chords throughout the entire tune. It sounds stiff and deadens the harmony. Instead, try drop 2 voicings for the main A sections. For the Fmaj7, play D in your left hand and F-A-C-E in your right. It creates space and lets the melody breathe. The C7alt on the turnaround is where most arrangements get interesting. Rather than a plain C7, try a C7#9 or C7b9. It resolves much cleaner into Fmaj7 because your ear expects that tension before the release. Another detail that trips people up: the ii-V in the second half of the A section. You see Dm7-G7 in the chord chart, but the melody implies a D7 sound over the Dm7 bar because of the C natural in the melody line. Playing a plain Dm7 voicing there sounds wrong even if the written chord says otherwise. Use D7alt or Dm7b5-G7 together and it clicks immediately.
Common Pitfalls and Where This Approach Fails
Lead sheets only give you the melody and chord symbols. If you are a beginner pianist who has never worked out improvisation or comping patterns before, the gap between reading the sheet and actually playing something musical is huge. You will read the tune perfectly but sound hollow when you try to accompany yourself. The workaround is learning the tune by ear first, then referencing the sheet music for details you forget. Even professional musicians do this with standards. Another hard limitation: tempo. At performance speed, the sixteenth-note feel in the right hand becomes difficult to articulate cleanly if your technique is not developed. Many arrange ments slow it down or simplify the right hand completely. If your goal is club gig speed, work it at 80% tempo first and only push to full tempo when every note lands evenly. Rushing this tune makes it sound sloppy fast. The bridge section in most arrangements modulates to C major temporarily. Some sheet music does not clearly mark this modulation and you end up playing in the wrong key for four bars. Check your arrangement against the original recording or a trusted transcription before you rely on it for a performance. I learned that the hard way at an open mic where I was twenty bars into the tune before I realized the sheet music had the bridge wrong.

Practical Learning Sequence
Start by memorizing the melody. Not reading it—actually having it in your head so you can sing it while you play. This tune is often used as a vocal standard, so understanding the melodic phrasing matters more than memorizing every chord symbol. Then learn the left hand walking bass line without the right hand. Once both are independent, combine them slowly. Add embellishments only after the basics are automatic. Expect about two to three weeks of consistent daily practice at twenty to thirty minutes per session to feel comfortable performing it. Less than that and you are reading the sheet music the whole time, which defeats the purpose of learning a standard this frequently played.
