Freedom ~ Love ~ Us

You said you want warmth and passion
You long for the ocean
I said I want cool and peace
I dream of the mountain

I see you when the sun sets
I think of you when the moon shines
I chase you in the rain
I can only reach you… in my dreams

I am here
but I am really gone
You are close
but you are no longer near

where is my next stop
the land of freedom
there’s no darkness, no walls
wind chimes with the song of souls

where is your next stop
the land of love
there’s no harm, no fear
scents of flowers perfusing the air

love of freedom
freedom of love
love of freedom
freedom of love

are we going to cross again
would i ever see you again


My 2nd composition is in A minor. Part of the inspirations was from Jay Chou’s (a Chinese pop singer and song writer) latest album November’s Chopin, but it doesn’t really sound like any of his songs. Actually people told me parts of it sounded like Yanni, the movie theme from Piano, the movie theme from John Woo’s… oh well, I guess there is not much character to the song, but I like it better than the first one. Here is the score in pdf.


Key transitions:

You can almost always find ways to transition from one key to another. If there is a common chord in the two keys, then find ways to progress from the tonic of the 1st key to the common chord, then move to the tonic of the 2nd key. Another two common schemes are:

  1. Move from the tonic of the 1st key directly to the dominant (major 5th) of the 2nd key
  2. Move from the tonic of the 1st major key to the minor 4th and then to the 2nd major key

Classical music, especially Chopin/Schubert/Schumann’s pieces, uses a lot of chord transitions. For example, Schubert’s music uses a lot of 3rd, e.g. 1-3-6

It is common to find transition between the major and the relative minor, e.g. between C major and A minor.

Chord transition allows the piece to extend in length and builds body.


This is my first music composition (named after this blog actually). Initially I wanted to write a song, but melody started to flow before the lyric. So I just made it a piano piece. It sounded as if I had some text in mind, but I wasn’t able to create any. There is no particular style to this piece. The harmony part is traditional, uninspired – I’d say. It’s my first attempt after all.

Here is the score in pdf, and in midi. It is created with Lilypond, an open-source music notation editor/processor. It is to writing music score what LaTex is to writing equations.

… a PowerPoint presentation should have ten slides (to cover ten topics), last no more than twenty minutes, and contain no font smaller than thirty points.The ten topics that a venture capitalist cares about are:

  1. Problem
  2. Your solution
  3. Business model
  4. Underlying magic/technology
  5. Marketing and sales
  6. Competition
  7. Team
  8. Projections and milestones

Business Model

04Jan06

Henry Chesbrough and Richar Rosenbloom give a definition and basic framework of “Business Model” in the following paper: The Role of the Business Model in Capturing Value from Innovation

Business model essentially deals with the problem of how to translate technology value into economic value, and how to capture and deliver the economic value. The basic components of a business model contain:

  1. Value proposition
  2. Market segment
  3. Value chain structure
  4. Revenue model
  5. Positioning
  6. Competitive strategy

Tonic key: the one which has a base quality, creates a sense of resolution
Dominant key: the one which has a leading quality to the tonic, gives a sense of direction
Sub-dominant key: the one which creates a sense of uncertainty

If tonic is noted as 1, then the dominant is typically the 5th, and subdominant is the 4th. That’s why the cadence is typically 1-4-5-1. And in classical works, most of the chords are consisted of 1/4/5’s. But sometimes there can be alternative dominant and sub-dominant keys, such as 1-2-7-1.
Tips on practice: focus in the problematic bar but completing a phrase with the context before and after, repeat and be patient. Don’t let your brain interfere with your hands too much, just listen and trust your body to do the right things after it gets accustomed to the pattern after repetitions. It is about to use your left brain!
Homework:
1) Bethovan Sonatina in G Major, second half
2) Bach Prelude in D Minor, second half


Rules of the 1-4-5-1 cadence:

1) The 5th is always major, regardless of whether the cadence is in major or minor, because of the leading tone

2) The 5th chord should progress down relative to the 4th

Read notes in groups of chords or patterns, and fully position hands before playing each group/bar

For a minor piece, the cadence can be in the corresponding major, e.g. D minor -> F major

For a major piece, the ending is in the tonic or dominant major.

Analyze notes by marking each bar with chords, and pay attention to the progression.

The French style with keys: recognize the absolute pitch of each key

The German style: sort of transposing everything to C major and D minor

Try to sing along when play each key, so get familiar with the pitch.

Each key actually produces different ambience, and the selection of key matters to a song. Typically when you have a melody formed in your head, the key is already determined. If it’s a song, the key also needs to match the singer’s voice.
