Why These Opening Bars Are Harder Than They Sound
The triplet arpeggios need to be perfectly even
The right hand plays continuous triplet arpeggios throughout the opening. Every note needs to be exactly the same volume and evenly spaced. Even small inconsistencies in timing or dynamics are immediately audible and break the hypnotic flow of the piece.
The left hand must sustain while the right hand plays
The left hand holds long bass notes and octaves that need to ring out underneath the right-hand arpeggios. Coordinating a sustaining left hand with a moving right hand requires independence between the two sides that takes slow, deliberate practice to develop.
The pedaling is critical and often wrong
The sustain pedal needs to change at each chord transition to avoid muddying the harmonies. Too early and you cut the previous chord short. Too late and the harmonies blur together. Getting clean pedal changes while keeping the arpeggios flowing is one of the hardest aspects of this piece.
How to Practice These Opening Bars
Open the pre-configured practice session
Click the button above to load PracticeLoop with the opening bars already looped from 0:00 to 0:30 at 50% speed.
Practice the triplet pattern hands separately
At half speed, play the right-hand triplet arpeggios alone until every note is perfectly even. Then practise the left-hand bass notes and octaves separately.
Focus on keeping all triplet notes equal in volume
Listen carefully - the third note of each triplet group often comes out weaker. At slow speed you can hear this clearly and correct it before it becomes a habit.
Work on smooth pedal changes at chord transitions
Add the sustain pedal and focus on changing it cleanly at each new harmony. The pedal should catch the new chord without blurring the old one into it.
Speed Progression Plan
Build up speed gradually. Only move on when the triplets are perfectly even and the pedaling is clean.
Train even triplets
Focus entirely on making each triplet note identical in volume and spacing. Practise hands separately first, then combine. No pedal yet.
Add the sustain pedal
Introduce pedal changes at chord transitions. Focus on clean changes - lift and depress the pedal at exactly the right moment to avoid muddying the harmonies.
Work on musical expression
Now bring in the dynamics and phrasing. The piece should breathe with subtle volume changes across phrases. Match the emotional arc of the original recording.
Full speed
Play along with the original. The arpeggios should flow like water with perfect evenness. If notes become uneven or pedaling muddies, drop back to 75%.
Practice Tips for These Opening Bars
Hands Separately First
Always start a practice session with each hand alone. The right-hand triplets and left-hand sustained notes each need individual attention before combining.
Even Triplets Are Everything
Record yourself and listen back. Uneven triplets are the most common problem. The third note of each group tends to be weaker - give it extra attention.
Pedal Changes at Chord Transitions
Change the sustain pedal at the moment a new chord begins. Lift and immediately depress - this catches the new harmony cleanly without blurring.

Frequently Asked Questions
Is Moonlight Sonata hard for beginners?
The first movement is often attempted by beginners because the tempo is slow and the notes are not extremely difficult individually. However, achieving the even triplets, proper hand independence, and clean pedaling that make it sound right requires intermediate-level control. Slowing it down further with PracticeLoop makes it much more accessible for developing these skills.
What speed should I start at?
Start at 50% speed. This gives you time to focus on making every triplet note perfectly even and developing clean pedal changes. Once it sounds smooth at 50%, move to 65%, then 75%, then full speed.
Can I loop tricky sections?
Yes. The pre-configured link loops the opening bars from 0:00 to 0:30. You can adjust the loop points in PracticeLoop to isolate any chord transition or passage that gives you trouble.
Does slowing down change the pitch?
No. PracticeLoop preserves the original pitch at all speeds. The piano sounds in tune whether you're playing at 50% or 100%, making it easy to play along.
