Galopas Nr. 1 Op.1.pdf

I took a break from composing for a while. Recently, I started composing again, and I would like to present my latest composition, an Impromptu, written between May and July 2026. Writing this piece proved challenging – choosing the right material was an endeavor, and most of the effort was spent on completing the coda section.

Anyway, I hope you enjoy it, and I would love to hear your thoughts!

Edit: I've included a 2nd mp3 rendition of the piece normalized to get rid of clipping.

I've given this piece a lot of thought over the years - most people I've shared it with enjoy it, although they disagree about which order is better (which I consider a success ). The most common criticism I've heard is that the individual variations are too short.

I'm curious - what do you all think? I've grown a lot ear-wise since I wrote this piece, even though I haven't written very much since college, but I'm still very happy with it for the most part. I'm thinking of revising the work and expanding some of the sections (e.g. N2, N3, S3) to give them a bit more symmetry. I might also try to get the work published, although I don't expect major publishing houses to be super interested or to get it to a wide audience.

Here is a pair of recordings I made of the piece right after I finished writing most of it, synced with the sheet music. I later added a cadenza to the opening of N1 which is not included in this recording.

Chiastic Variations, Op. 6a

Chiastic Variations, Op. 6b

This is my first composition post here. I would be very grateful for honest feedback on a solo piano piece called Pachelbel’s Keygen — Ascent to Elevation 100.

A little context about me: I am a software and game designer, not a trained composer or an accomplished pianist. I have no formal education in harmony, counterpoint, or composition. I made this piece largely by ear and through experimentation with MIDI, then produced the score in MuseScore. It's not obvious to me that I have any musical talent at all, actually. But I need this piece to be good for a project I am working on.

Because of that, I suspect there may be errors or missed opportunities that I simply do not have enough musical experience to recognize. I am posting here because I would like criticism from people who know more than I do—not merely reassurance that it sounds pleasant.

The piece lasts approximately 5 minutes and 40 seconds. It uses the familiar ground bass from Pachelbel’s Canon and passes through a series of increasingly elaborate eight-bar stages, which I call “Elevations.”

The general progression is:

• the initial signal and subject

• introduction of the ground bass

• canon and additional contrapuntal voices

• inversion and mirrored material

• increasingly dense recursive treatment

• an intentionally excessive virtuosic summit

• destabilization, fragmentation, and eventual reconvergence

The idea is that the piece is being progressively “overclocked.” It was composed partly for an open-source piano-practice application I am developing, so the clearly separated stages and steadily increasing technical difficulty are intentional parts of the concept.

However, I do not want the concept to serve as an excuse for weak composition. I would like the piece to hold up as music independently of the software.

I would especially appreciate feedback on any of the following:

1. Are there problems in the harmony, voice leading, counterpoint, register, rhythm, or notation that seem like mistakes rather than deliberate choices?

2. Do the successive Elevations genuinely develop the material, or do some of them merely add more notes and difficulty?

3. Does the main subject remain perceptible as the texture becomes denser?

4. Are there places where the material presents an obvious opportunity for a stronger variation, reharmonization, transition, or climax that I failed to use?

5. Does the post-summit destabilization feel like a natural consequence of the ascent, or does it feel like a separate ending attached to the piece?

6. Is the piano writing convincingly virtuosic, or are passages simply awkward, impractical, or poorly divided between the hands?

7. Are any sections redundant, overlong, underdeveloped, or insufficiently differentiated from the sections around them?

Please feel free to be direct. I am particularly interested in criticisms that distinguish between:

• definite craft or notation problems

• important opportunities for improvement

• legitimate differences in personal taste

Measure numbers and concrete alternatives would be extremely helpful. I may need to ask questions when terminology is unfamiliar to me, but I will take the criticism seriously.

The attached MP3 is a computer-rendered reference performance rather than a recording by a pianist. I have also attached the PDF score. I understand that the rendering may have limitations, so I would appreciate help distinguishing playback problems from problems actually present in the writing.

Thank you very much for listening and for any observations you are willing to share.

Although, I feel as though it may be a bit too repetative, despite having variation in both rhythm, chord voicing, chord progression choice, including a modulation towards the end middle. I'm seeking to build upon the ideas I have in this score, more effectively. Any suggestions are welcome :)

Updated again 6/26/26 - New score files attached.

**FINAL UPDATE**

Score files updated to reflect finalized changes to this score. I elected to change the key from it's original C minor to B minor, as I felt that the theme of this score matched the more melancholy sound of B minor best. All changes published and submitted as of 7/10/2026

This time I focused on a more rewritten exposition like introduction that is connected to the material later and tried to make it more cohesive overall.

Any feedback is welcome.
Thanks in advance.

How are you?

I would like to share my latest composition with you. This time, it is a variation on an old Czech hymn "Vstalť jest této chvíle".

I’d really appreciate it if you gave it a listen. Thank you!

Romantic Prelude in A minor.pdf

I composed this short waltz for piano today. I'm still practicing it, so for now I've used the sounds from MuseScore 4.

It was inspired by Tchaikovsky's Album for the Young, Op. 39. The opening melodic motif is quite similar to that of No. 8, "Waltz," and I also used some harmonic progressions that I learned from No. 14, "Polka."

While studying and practicing pieces from that album, I started wanting to compose several short piano pieces and create my own "Album for the Young."
This is my first attempt. It is a waltz in B-flat major, although the tonal center shifts around quite a bit.

The form is ABA', with A being the main waltz theme and B a slower lyrical brief section in Cmaj.

As always, every feedback, comment or suggestion is more than welcome and hope you enjoy it! Thank you!

Edit: After I posted I submitted this piece in a competition that required me to make it private on my youtube channel. Sorry for the confusion, I'll now provide the recording and I might re-edit this post including the youtube video uploaded by the competition channel.

Edit 2: The video is out on the channel of the competition so I'm sharing the link.

I've removed the lyrics for seriousness' sake in the PDF, but I hope you'll find something of interest in here. As usual, I am also always looking for feedback and ways to keep chipping away at my pieces even after I've written them. Are the two main themes different enough in character? Does the form feel awkward or bloated? Anything else of concern or note? One thing I will admit is that I probably should not have notated swing entirely with triplets, so that's something I've started to fix up at the moment...
